PROBLEM TO BE SOLVED: To suppress a temperature rise of a wavelength conversion member and improve light emission efficiency.SOLUTION: A lighting device includes a wavelength conversion member 11 containing a wavelength conversion substance which, when a first light L1 is irradiated, emits a second light L2 of a different wavelength from the first light and a supporting member 12 which supports a surface of an opposite side to an emission face of the second light of the wavelength conversion member and discharges heat generated in the wavelength conversion member, and a light transmitting member 13 which is adhered tight to the wavelength conversion member and the supporting member and is made of a material of which the thermal conductivity is higher than the wavelength conversion member. |
