1. A blood pressure measurement device comprising:
a base;
a flow path cover that is fixed to the base and defines a flow path portion with reference to the base;
a rib that is on a base side of the flow path cover and that is fixed to the base, the rib forming the flow path portion;
a recess that is arranged in an area surrounded by the rib of the flow path cover and that includes (i) a first outer surface, which is on the base side of the flow path cover and part of which is projected toward the base, and (ii) a second outer surface, which is on a side of the flow path cover opposite to the base side and part of which is depressed toward the base, the recess formed in the flow path cover such that the recess projects on a side of the base, and projections abut the base and are provided to maintain a gap between the first outer surface and the base;
a nozzle that is formed on the second outer surface of the recess and communicates with the flow path portion;
a cuff that is connected to the nozzle and that is inflated when a fluid is supplied to an internal space; and
a pump that supplies the fluid to the internal space of the cuff;
wherein the base holds the pump.
