Abstract
A light emitting device includes a base member, a laser element, a retaining member, a fluorescent member, and first and second fixing members. The retaining member has a first surface on a laser element side and a second surface not on the laser element side. The fluorescent member is fixed to a through hole of the retaining member. The first and second fixing members clamp the retaining member. The first and second fixing members have first and second contact surfaces in contact with the first and second surfaces of the retaining member, respectively. A distance between the first and second contact surfaces becomes smaller as the first and second contact surfaces become farther from the through hole. The retaining member, the first and second fixing members are arranged such that a space surrounded by the retaining member, and the first and second fixing members exists around the retaining member.
