In the reflective light emitting device, the use efficiency of fluorescence is improved. The light emitting device (1) includes a light emitting unit (11) including phosphor particles (P) that emits fluorescence upon receiving laser light (E), and a substrate (12) that supports the light emitting unit (11) and the light emitting unit (11). The transparent material film (13) with the end portion (A) exposed and a light projecting member facing the end portion (A), and the laser beam (E) is emitted from the light emitting portion (11). ) Of the excitation light irradiation surface (S) opposite to the side facing the transparent material film (13).反射型の発光装置において、蛍光の利用効率を向上させる。発光装置（１）は、レーザ光（Ｅ）を受け蛍光を発する蛍光体粒子（Ｐ）を含む発光部（１１）と、発光部（１１）と発光部（１１）を支持する基板（１２）との間に配され、端部（Ａ）が露出された透明材料膜（１３）と、端部（Ａ）に対向する投光部材とを備え、レーザ光（Ｅ）は、発光部（１１）の、透明材料膜（１３）と対向する側とは反対側の励起光照射面（Ｓ）に照射される。
