Abstract:
A light-emitting device according to an embodiment of the present invention includes a light-emitting element, and a package substrate on which this light-emitting element is placed. This package substrate includes a placement face on which the light-emitting element is placed, a back face that is opposed to the placement face, and a mounting face that is opposed, between the placement face and the back face, to a mounting substrate when the light-emitting device is mounted, and includes a first recess portion that extends, on the mounting face, from the back face toward the placement face and that has a first heat conduction member formed on the surface thereof, and an intermediate heat conduction member for conducting heat between the light-emitting element and the first heat conduction member.
