An optical touch module includes a frame having an assembling wall and a plurality of side walls, and an operating space. The assembling wall has an inner wall face. A display device is disposed inside the frame, and an interval is formed between a margin of the display device and the inner wall face and spatially communicates with the operating space. At least a light sensing device located inside the interval has a fixed part and a detection part. At least a signal processing device is electrically connected to the At least alight sensing device. At least a reflective element has a reflective surface located at a same horizontal plane as the detection part and facing toward the operating space. The optical touch module of the present invention is able to be calibrated or repaired at a front frame of the display device without causing damages to the display device.
