Abstract: An optical wavelength converter (1) is configured such that an optical wavelength conversion member (9) is bonded to a heat dissipation member (13) having superior heat dissipation property. Thus, heat generated by light incident on the optical wavelength conversion member (9) can be efficiently dissipated. Therefore, even when high-energy light is incident on the optical wavelength converter, temperature quenching is less likely to occur, and thus high fluorescence intensity can be maintained. An intermediate film (21) is disposed between a reflective film (19) and a bonding portion (15). The presence of the intermediate film (21) improves the adhesion between the reflective film (19) and the bonding portion (15), thereby enhancing the heat dissipation from the optical wavelength conversion member (9) to the heat dissipation member (13). Thus, the temperature quenching of the optical wavelength conversion member (9) can be prevented, thereby enhancing fluorescence intensity.
