Claim 1:
2. The sphygmomanometer according to claim 1, wherein:
the cuff structure includes:
a bag-shaped pressure cuff that is configured to extend along the circumferential direction of the wrist as the measurement target site so as to receive a supply of the fluid as a pressurization fluid to press the wrist as the measurement target site,
a sensing cuff that is configured in a bag shape so as to be configured to contain a pressure transmission fluid, is disposed along an inner circumferential surface of the pressure cuff, and is configured to extend in the circumferential direction across an artery passing portion of the wrist as the measurement target site, and
a back plate that is inserted between the pressure cuff and the sensing cuff, the back plate being configured to extend along the circumferential direction of the wrist as the measurement target site so as to transmit a pressing force from the pressure cuff to the sensing cuff, and

the programmed processor is configured to perform control of supplying the fluid as the pressurization fluid from the pump to the pressure cuff to press the wrist as the measurement target site, and the programmed processor is configured to calculate a blood pressure based on a pressure of the pressure transmission fluid contained in the sensing cuff.
