To provide a light source reflector capable of preventing the removal of a reflective film.SOLUTION: Provided is a reflector 40 used in a light-emitting part of an optical sensor unit of a discrimination part built in a bill handling part of an automatic transaction device. A multiple-reflector plate provided with the plurality of reflectors is cut along dicing lines so as to be divided into individual pieces. The reflector comprises: a peripheral surface 70; an inclined surface 67 provided with a reflective film 68 which is surrounded by the peripheral surface and is inclined to the peripheral surface so as to reflect light; and a suppressing pattern inclined surface 71 which is provided with at least one second edge line part RL2 having the reflective film formed between an end surface 73 and the peripheral surface.SELECTED DRAWING: Figure 8 【課題】反射膜の剥がれを抑止可能な光源用反射体を提供する。【解決手段】自動取引装置の紙幣取扱部に組み込まれる鑑別部の各光学センサユニットの発光部におけるリフレクタ４０は、複数のリフレクタが形成された複数リフレクタ板からダイシングラインにおいて切断され個別に分割されるリフレクタにおいて、周囲面７０と、周囲面に囲まれ周囲面に対し傾斜して光を反射する反射膜６８が形成された傾斜面６７と、端面７３と周囲面との間に反射膜が形成された少なくとも１つの第２稜線部ＲＬ２が形成された抑止パターン傾斜面７１とを設ける。【選択図】図８
