A pulsebeat measurement apparatus includes a first temperature detector configured to detect a temperature of a human body a second temperature detector, having the same characteristic as that of the first temperature detector, configured to detect a temperature of the human body a heat accumulator, contacting the second temperature detector, configured to suppress a change in temperature of the second temperature detector a specifying unit configured to specify a period of a change in temperature caused by a pulsation of the human body based on a difference between the temperature of the human body detected by the first temperature detector and the temperature of the human body detected by the second temperature detector and a pulsebeat measurement unit configured to measure a pulsebeat based on the specified period of the change in temperature.
