Among the technical characteristics disclosed in this specification, the pulse wave sensor with one of the technical characteristic includes a construction to detect the pulse wave at a wrist (i.e., a construction to measure the pulse wave to be worn at the wrist). To be more concrete, the pulse wave sensor includes a measurement unit to measure the pulse wave, a power source unit to supply power to the measurement unit, a cable to connect between the measurement unit and the power source unit electrically, and a armlet type housing to contain the measurement unit, the power source unit, and the cable.

A wireless plethysmogram sensor unit is capable of obtaining a plethysmogram from a living tissue of a measuring object and of transmitting the plethysmogram to a processing unit outside the wireless plethysmogram sensor unit. The sensor unit includes a light source to emit measuring light into the living tissue and a light receiving element to receive light emerging from the tissue, which is accompanied by pulsation caused by absorption by arteries in the tissue. A memory stores a plethysmogram obtained in accordance with the light received by the light receiving element. A short range wireless communicator transmits the plethysmogram to the processing unit. A power source provides power to other elements in the sensor unit, and a controller controls the elements of the sensor unit.
