This invention provides an optical sensor module, which comprises a lead frame, a light-receiving unit, and at least one light-emitting unit. The lead frame includes a plate and at least one of side plate. The plate has a carrier portion and a protrusion portion protruding forward the side plate. The side plate is disposed apart from the protrusion portion. The light-receiving unit includes a photodetector disposed on a carrier surface of the carrier portion and having a light-receiving surface and a first light-blocking wall encircling the carrier portion for defining a first opening. The light-emitting unit includes a light-emitting device disposed on a mounting surface of the side plate and having a light-emitting surface and a second light-blocking wall encircling the side plate for defining a second opening. The first light-blocking wall or the second light-blocking wall encapsulates the protrusion portion. An upper surface of the protrusion portion is not lower than the light-emitting surface. This invention also provides a wearable device which has the optical sensor module stated above.一種光感測器模組,包含一導線架、一接收單元,及至少一發光單元。導線架包括一板體,及至少一側板體。板體具有一承載部,及至少一由承載部向側板體凸伸的凸出部。側板體與凸出部間隔設置。接收單元包括一設置於承載部上的一承載面上並具有一收光面的光接收件,及一環圍承載部以定義出一第一開口的第一擋光壁。發光單元包括一設置於側板體上的一設置面上並具有一出光面的發光件,及一環圍該側板體以定義出一第二開口的第二擋光壁。其中第一擋光壁或第二擋光壁包覆凸出部且凸出部的一頂面不低於出光面。本發明亦提供一種前述光感測器模組的穿戴裝置。21‧‧‧承載部211‧‧‧第一側213‧‧‧承載面214‧‧‧背面22‧‧‧凸出部221‧‧‧頂面222‧‧‧傾角段223‧‧‧連接段224‧‧‧擋光段311‧‧‧設置面424‧‧‧水平區425‧‧‧防溢膠區43‧‧‧第一透明封裝膠5‧‧‧發光單元50‧‧‧第二開口51‧‧‧發光件511‧‧‧出光面512‧‧‧導線52‧‧‧第二擋光壁521‧‧‧頂面4‧‧‧接收單元40‧‧‧第一開口41‧‧‧光接收件411‧‧‧收光面412‧‧‧導線42‧‧‧第一擋光壁421‧‧‧頂面422‧‧‧內圍面423‧‧‧傾斜區522‧‧‧內圍面523‧‧‧傾斜區524‧‧‧水平區525‧‧‧防溢膠區53‧‧‧第二透明封裝膠A‧‧‧高度B‧‧‧高度C‧‧‧高度
