Abstract
A light-emitting device includes lead frames, a light-emitting element placed on a bottom of a recessed portion formed at one of the lead frames, and a light-transmitting resin covering the light-emitting element. The lead frames have a covered region which is covered with the light-transmitting resin and an exposed region exposed out of the light-transmitting resin. The light-emitting device has a gap between the lead frame and the light-transmitting resin at an inner side surface of the recessed portion, the gap having a width longer than a main wavelength of light from the light-emitting element. The lead frame is in close contact with the light-transmitting resin at an end of the covered region, which is located in a boundary with the exposed region or in the vicinity of the boundary within the covered region.
