PROBLEM TO BE SOLVED: To provide a technology which can stably hold a baseboard and a light distribution control element without collapsing a positional relationship between a spot light source and a light emission part of the light distribution control element without installing a holding structure at the light distribution control element.SOLUTION: A holding structure of a light distribution control element 1 comprises: a long-length mounting baseboard 2 on which a plurality of LED elements 2a are aligned, and which has a plurality of notches 2b; the light distribution control element 1 mounted to the mounting baseboard 2, and arranged on each LED element 2a; and holding members 3 which are arranged at positions corresponding to a plurality of the notches 2b, and hold the mounting baseboard 2 and the light distribution control element 1.SELECTED DRAWING: Figure 2 【課題】配光制御素子に保持構造を設けることなく、点光源と配光制御素子の出光部との位置関係を崩さずに基板と配光制御素子とを安定して保持することが可能な技術を提供することを目的とする。【解決手段】配光制御素子１の保持構造は、複数のＬＥＤ素子２ａが配列状に実装され、かつ、複数の切欠き部２ｂを有する長尺状の実装基板２と、実装基板２に実装された各ＬＥＤ素子２ａ上に配置される配光制御素子１と、複数の切欠き部２ｂに対応する位置に配置され、かつ、実装基板２と配光制御素子１とを保持する保持部材３とを備えている。【選択図】図２
