A headlamp 1 includes (i) a laser element 2 for emitting a laser beam, (ii) a light emitting section 4, including a sealing material made from an inorganic material, for emitting fluorescence upon receiving the laser beam emitted from the laser element 2, and (iii) a heat sink 7 for releasing, via a contact surface of the heat sink 7 which contact surface is in contact with the light emitting section 4, heat generated in the light emitting section 4 in response to the laser beam emitted onto the light emitting section 4, the light emitting section 4 existing within a range which is determined on the basis of the contact surface and with which desired heat releasing efficiency is obtained.
