Claim 8:
9. The light source device according to claim 2, wherein
the light source device includes a plurality of light emitting elements opposite to each other,
the wavelength-selective reflecting member is between the Plurality of light emitting elements, and
the wavelength-selective reflecting member includes:
a first reflecting portion configured to:
partially reflect first excitation light emitted from a first light emitting element of the plurality of light emitting elements, wherein the first excitation light is partially reflected to be guided to the phosphor, and
transmit the first excitation light reflected by the phosphor and fluorescence emitted from the phosphor based on excitation by the incidence of the first excitation light on the phosphor, and

a second reflecting portion configured to:
partially reflect second excitation light emitted from a second light emitting element of the plurality of light emitting elements, wherein the second excitation light is partially reflected to be guided to the phosphor, and
transmit the second excitation light reflected by the phosphor and fluorescence emitted from the phosphor based on excitation by the incidence of the second excitation light on the phosphor, wherein
the first reflecting portion is configured to partially reflect the second excitation light that is transmitted through the second reflecting portion and guided to the first reflecting portion, and
the second reflecting portion is configured to partially reflect the first excitation light that is transmitted through the first reflecting portion and guided to the second reflecting portion.
