To reduce light leakage in an injection molded object.SOLUTION: A lamp 1 has: a housing 2 provided with an accommodation part 2a and made of an opaque resin material that does not transmit light; a lens 3 covering the accommodation part 2a and being in contact with the housing 2; a resin joint material 9 for joining the housing 2 and the lens 3; and encapsulated members such as an inner lens member (a light guide member) accommodated in the accommodation part 2a, an LED and a substrate. Furthermore, the lens 3 is provided with: a light transmitting part 3d made of a resin material that transmits light; and a non-light transmitting part 3f that is joined to the housing 2, and does not transmit light. The light transmitting part 3d is arranged so as to face the inner lens member.SELECTED DRAWING: Figure 2
【課題】射出成形体において漏光の低減化を図る。【解決手段】ランプ1は、収容部2aが設けられ、かつ、光を透過させない不透明な樹脂材料からなるハウジング2と、収容部2aを覆い、かつ、ハウジング2と当接するレンズ3と、ハウジング2とレンズ3とを接合する樹脂接合材9と、収容部2aに収容されたインナレンズ部材(導光部材)、LEDおよび基板等の封入部材と、を有する。さらに、レンズ3は、光を透過させる樹脂材料からなる透光部3dと、ハウジング2と接合され、かつ、光を透過させない不透光部3fと、を備えており、透光部3dは、上記インナレンズ部材と対向して配置されている。【選択図】図2
