A light source device includes a first light source configured to emit first light having a first wavelength, a second light source configured to emit second light, a wavelength conversion element having a first surface which the second light emitted from the second light source enters and a second surface located at an opposite side to the first surface, and configured to convert the second light into third light having a second wavelength, an optical member configured to combine the first light and the third light to emit combined light, and a reflecting member configured to reflect, toward the optical member, the first light which is a part of the first light emitted from the first light source and which is emitted from the optical member. The first light reflected by the reflecting member enters the second surface via the optical member, and is converted into the third light.
