PROBLEM TO BE SOLVED: To suppress deterioration of luminous intensity or luminance when light is incident on an optical wavelength conversion material from a light-emitting element.SOLUTION: In a light-emitting module 40, an optical wavelength conversion member 50 is formed in a plate shape and arranged such that an incident surface 50a faces a light-emitting surface 48a of a semiconductor light-emitting element 48. The optical wavelength conversion member 50 converts a wavelength of light incident from the incident surface 50a and emits the converted light. Recessed and projecting parts are formed on the incident surface 50a of the optical wavelength conversion member 50. An adhesive layer 52 is formed between the light-emitting surface 48a of the semiconductor light-emitting element 48 and the incident surface 50a of the optical wavelength conversion member 50. The adhesive layer 52 is formed to get into the recessed parts of the incident surface 50a and fixes the semiconductor light-emitting element 48 and the optical wavelength conversion member 50 to each other. |
