A mouse capable of detecting a pulse includes: a) a housing having electronic elements therein for fulfilling the functions of the conventional mouse, an infrared pulse sensor being disposed at the internal side of the housing for detecting the change of a slight amount of blood within the blood vessel of a user's thumb that is caused by the pulsation such that the pulse signal of the user is available; b) a control switch disposed at the internal side of the housing for turning on or off the infrared pulse sensor; c) a noise canceling circuit and a filtering shaping amplifying circuit coupled to the pulse sensor; and d) a microprocessor adapted to calculate the number of the heartbeat according to the pulse signal inputted by the filtering shaping amplifying circuit, the heartbeat signal being transmittable from a signal output terminal to a signal input terminal of a computer. Accordingly, the heartbeat signal is then received by a central processing unit (CPU) of the computer so that the user's physiological state is displayable on a display.
