This invention provides an optical sensor module, which includes a supporting frame, a light-receiving unit, and two light-emitting units. The supporting frame comprises a main base and two side bases which are angled with the main base. . The light-receiving unit comprises a photodetector which is disposed on the main base and a first light-blocking layer which surrounding the photodetector and connecting the side bases. The photodetector has a light-receiving surface, and the first light-blocking layer has an opening that corresponding the light-receiving surface. Each of the light-emitting unit has a light-emitting device which has a light-emitting surface. Defining a first line which is perpendicular to the light-receiving surface, the light which is emitted from the light-emitting unit is focused to the first line. In addition, this invention also provides a wearable device which has the optical sensor module.一種光感測器模組,包含一支撐架、一接收單元,及二發光單元。支撐架包括板體,及二位於板體的相對兩側,並與板體成一角度設置的側板體。接收單元包括設置於板體上的光接收件,及包覆光接收件並連接側板體的第一擋光層,光接收件具有位於板體相反側的收光面,第一擋光層具有對應收光面的開口。發光單元設置於側板體上,每一發光單元包括具有出光面的發光件,定義垂直收光面的第一直線,發光單元發出的光往第一直線集中。本發明還提供一種具有該光感測器模組的穿戴裝置。100‧‧‧使用者2‧‧‧光感測器模組216‧‧‧側板體部224‧‧‧側面225‧‧‧收光面235‧‧‧出光面31‧‧‧罩殼311‧‧‧透明外蓋4‧‧‧電路板5‧‧‧處理單元6‧‧‧穿戴裝置L‧‧‧第一直線N‧‧‧法線θ‧‧‧夾角X‧‧‧距離Y‧‧‧距離I1‧‧‧直線I2‧‧‧直線
