PROBLEM TO BE SOLVED: To provide a bulb type luminaire having a reliability and capable of reducing a process cost of assembly and a spoilage cost due to failure.SOLUTION: A bulb type luminaire includes: a light-emitting body including a semiconductor light-emitting element; a power supply substrate for driving the light-emitting body; a mouth piece being a power supply part to the power supply substrate; a heat radiation body radiating heat generated in the light-emitting body to the outside; and a holder collecting light emitted from the light-emitting body, and pressing the light-emitting body against the heat radiation body. The holder has a screw hole, and a truncated pyramid-shaped engagement part formed outside the screw hole of a surface on the light-emitting body side, and engaged to the light-emitting body to prevent positional deviation.SELECTED DRAWING: Figure 2 【課題】本発明は、信頼性及び組立ての工程コスト及び不良による仕損費を低減することが出来るように構成した、電球型照明装置を提供することを目的とする。【解決手段】半導体発光素子を備えた発光体と、前記発光体を駆動するための電源基板と、前記電源基板への給電部になる口金と、前記発光体から発生した熱を外部に放熱するための放熱体と、前記発光体から放出された光を集光させ、また、前記発光体を前記放熱体に押圧するためのホルダを有し、前記ホルダには、ねじ孔と、前記発光体側の面の前記ねじ孔の外側に形成され、前記発光体と係止し位置ずれを防止するための角錐台状の係止部を有することを特徴とする。【選択図】図２
