PROBLEM TO BE SOLVED: To provide a sphygmomanometer capable of accurately measuring the air temperature in a measurement environment with an inexpensive configuration. A sphygmomanometer including a main body 20 including a pump and a cuff to which air is supplied from the pump includes a temperature sensor 28 for measuring air temperature, and a case body 30 for accommodating the pump and the temperature sensor. The case body is provided with an outside air introduction hole 40 for communicating the storage space S for accommodating the temperature sensor to the outside of the case body.
