SPHYGMOMANOMETER

A sphygmomanometer includes a casing including a base and a side wall surrounding the base, a circuit board provided in the casing, a piezoelectric pump located in the casing and including a nozzle of which gas is jetted out, a first lead wire and a second lead wire each having one end electrically connected to the piezoelectric pump and an other end electrically connected to the circuit board, and a first rib and a second rib each projecting from the base toward the inside of the casing. A direction in which the first rib and second rib project is substantially parallel to a direction in which the nozzle extends. The first lead wire is press-fitted between the side wall and the first rib, and the second lead wire is press-fitted between the first rib and the second rib.
