摘要:
A substrate includes a storage portion which is defined by a base for mounting a light emitting element and a wall portion standing up on and from the base. A package is structured such that the upper end of the wall portion so formed as to surround the periphery of the storage portion is connected to a cover to thereby seal a light emitting element. A seal structure is composed of an uneven portion formed on the lower surface side surface of the base, a close contact layer formed on the surface of the uneven portion, a power supply layer formed on the close contact layer, and an electrode layer formed on the surface of the power supply layer. The uneven portion includes a first recessed portion formed at a position spaced in the radial direction from the outer periphery of a through electrode or from the inner wall of a through hole, and a second recessed portion formed at a position spaced further outwardly from the first recessed portion.

A method of producing a light emitting apparatus including a light emitting element, a light emitting element housing having a recess for housing the light emitting element, and a translucent substrate placed on the light emitting element housing is disclosed. The disclosed method includes a fluorescent-substance-containing resin forming step of forming a fluorescent-substance-containing resin on a first side of the translucent substrate which first side is opposite to a second side of the translucent substrate which second side faces the recess. In the fluorescent-substance-containing resin forming step, luminance and chromaticity of light that is emitted from the light emitting element and then transmitted by the fluorescent-substance-containing resin are measured and a thickness of the fluorescent-substance-containing resin is adjusted based on the measured luminance and chromaticity so that light emitted from the light emitting apparatus attains the specified luminance and chromaticity.
