摘要:
A light emitting apparatus comprising a light emitting device (101) disposed on a supporting body (105), and coating layers ((108, 109) that bind a fluorescent substance that absorbs light emitted by the light emitting device (101) and emits light of a different wavelength and secures the fluorescent substance onto the surface of the light emitting device (101). The coating layers (108, 109) are made of an inorganic material including an oxide and a hydroxide, each containing at least one element selected from the group consisting of Si, Al, Ga, Ti, Ge, P, B, Zr, Y, Sn, Pb and alkali earth metals. Also an adhesive layer (110) is made of the same inorganic material as that of the coating layers (108, 109).
