摘要： An optical wavelength conversion device includes an optical wavelength conversion member configured to convert the wavelength of incident light; a heat dissipation member which is more excellent in heat dissipation than the optical wavelength conversion member; and a joint portion which joins the optical wavelength conversion member and the heat dissipation member together. The optical wavelength conversion member includes a plate-shaped ceramic fluorescent body and a reflecting film disposed on a heat dissipation member-side surface of the ceramic fluorescent body. The joint portion has a thermal conductivity of 120 W/mK or more. The joint portion has a melting point of 240° C. or higher.

摘要： A wavelength conversion member includes a ceramic fluorescent body for converting a wavelength of incident light, a heat radiation member for radiating heat of the ceramic fluorescent body to an outside atmosphere, and a solder layer for joining together the ceramic fluorescent body and the heat radiation member. The solder layer includes a joining portion disposed between the ceramic fluorescent body and the heat radiation member and a protruding portion protruding outward from an outer circumferential portion of the ceramic fluorescent body. The protruding portion is spaced apart from a side surface formed on the outer circumferential portion of the ceramic fluorescent body. In the solder layer, the maximum value of thickness of the protruding portion is greater than the average value of thickness of the joining portion.

摘要： There is provided a wavelength conversion member including: a fluorescent body and a reflective film. The fluorescent body is configured to emit fluorescence by an excitation light and has an incident surface into which the excitation light comes and a rear surface which faces the incident surface. The reflective film is arranged on a side of the rear surface of the fluorescent body and includes a metal layer and ceramic particles dispersed in the metal layer. The ceramic particles are crystalline, and a melting point of the ceramic particles is higher than a melting point of a metal constructing the metal layer.

摘要： A fuel cell with separator includes a fuel cell body having a cathode, an anode, and a solid electrolyte layer disposed between the cathode and the anode; a plate-like metal separator having first and second main surfaces and an opening which opens at the first and second main surfaces; a joint formed of an Ag-containing brazing filler metal and adapted to join the fuel cell body and the first main surface of the metal separator; and a seal formed of a glass-containing sealing material and disposed closer to the opening than is the joint, the seal being located between the first main surface and the fuel cell body and extending along the entire perimeter of the opening.
