A laser timer is provided to enable a user to easily recognize a time by arranging a diffusion light receiver at an irradiation point of a laser diode. A laser timer includes a timer(100), a fixing unit(150), and a laser diode(200). The timer is implemented on a fixed housing. The fixing unit fixes the timer on an implementation position. When the timer is expired, light is irradiated on a set point, while the laser diode is fixed on the fixing unit. The laser diode is integrated with the housing, such that the laser is easily recognized. A diffusion light receiver, which is implemented on a propagation point, receives laser beams from the laser diode and diffuses the light.
