Abstract
A light-emitting-element mounting package includes a substrate including front and back surfaces, a lead pin disposed at the back surface of the substrate, and a ceramic plate including an opposing front surface that opposes the back surface of the substrate and an opposing back surface. The substrate has a first through hole that extends therethrough. The ceramic plate has a second through hole that extends therethrough. Conductive portions extend continuously within the second through hole and around openings of the second through hole in the opposing front and back surfaces. A flange portion of the lead pin is joined to the conductive portion at the opposing back surface. A conductive member is joined to the conductive portion at the opposing front surface. The ceramic plate is joined to the back surface of the substrate with a portion of the conductive member disposed in the first through hole.
