Abstract
A sphygmomanometer includes a cuff and a main body. The main body is equipped with a substrate, a pump and a pressure sensor that are attached to one surface of the substrate, and a plate-shaped member opposed to an other surface of the substrate on an opposite side of the one surface of the substrate. The substrate includes a first through-hole and a second through-hole. The other surface of the substrate and an opposing surface of the plate-shaped member opposed to the other surface constitute the planar direction passage extending in a planar direction along the other surface of the substrate. The planar direction passage communicates with a fluid bag of the cuff. The sphygmomanometer further includes a pressurization controller and a blood pressure calculator. The pressurization controller controls pressing the measured site through the planar direction passage. The blood pressure calculator calculates a blood pressure.
