LIGHT SOURCE DEVICE AND PROJECTOR

PROBLEM TO BE SOLVED: To provide a light source device capable of reducing damage and/or falling-off of a translucent member.SOLUTION: A light source device 1 includes: a base material constituted of a metal material; a plurality of light-emitting elements provided on a first surface of the base material; a frame provided so as to surround the plurality of light-emitting elements on the first surface of the base material; and a translucent member being provided on a surface of an opposite side to the surface provided with a base material of the frame, and transmitting light emitted from the plurality of light-emitting elements. The frame has a dimension in which a cross-section coefficient in a cross-section shape of the frame is equal to 0.5 mmor more and equal to 7.0 mmor less.SELECTED DRAWING: Figure 1 【課題】透光性部材の破損や脱落の低減が可能な光源装置を提供する。【解決手段】本発明の光源装置１は、金属材料で構成された基材と、基材の第１面に設けられた複数の発光素子と、基材の第１面に複数の発光素子を囲んで設けられたフレームと、フレームの基材が設けられた面と反対側の面に設けられ、複数の発光素子から射出された光を透過させる透光性部材と、を備え、フレームは、フレームの断面形状における断面係数が０．５ｍｍ３以上、７．０ｍｍ３以下となる寸法を有する。【選択図】図１
