PROBLEM TO BE SOLVED: To provide a light emitting device which maintains a constant distance between a light emitting element and a transparent material regardless of a direction of the light emitting device, prevents light from the light emitting element from leaking to the outside, and enables improvement of the quality without increasing the number of components.SOLUTION: A light emitting device 10 includes: a substrate 14 on which a light emitting element 12 is mounted; a case 22 in which the substrate 14 is disposed; and a cover part 24 which is attached to the case 22 while contacting with a mounting surface 16 of the substrate 14 to position and hold the substrate 14. The cover part 24 includes a cylindrical part 80 in which a transparent material 25, to which the light emitted from the light emitting element 12 is guided, may be attached. First stopper parts 86a, 86b, which block movement of the transparent material 25 to the side where the substrate 14 is positioned, and second stopper parts 92a, 92b, which block movement of the transparent material 25 to the opposite side of the side where the substrate 14 is positioned, are formed on an inner surface of the cylindrical part 80.SELECTED DRAWING: Figure 8
【課題】発光装置の向きによらず発光素子と導光体の距離を一定に保持することができると共に、発光素子からの光が外部に漏れることを阻止し、併せて部品点数の増加を招くことなく品質を向上させることができる発光装置を提供する。【解決手段】発光装置10は、発光素子12が実装された基板14と、内部に該基板14が配設されるケース22と、該基板14の実装面16に当接した状態で該ケース22に装着することにより該基板14を位置決め保持するカバー部24とを備える。カバー部24は、発光素子12から発光された光が導かれる導光体25を内部に装着可能な筒部80を備え、その内面には、導光体25の基板14が位置する側の移動を阻止する第1ストッパ部86a、86bと、該導光体25の基板14が位置する側とは反対側の移動を阻止する第2ストッパ部92a、92bとが形成されている。【選択図】図8
