Abstract:
The present invention can provide a sensor module and a blood pressure measurement device that improves the protection strength of and prevents damage to a surface that comes into contact with a living body. A sensor module 63 of a blood pressure measurement device 1 includes: a sensor base 72; a pressure sensor portion 71 fixed to the sensor base 72; a sensor head cover 73 fixed to the sensor base 72, the sensor head cover 73 forming a gap portion 79 between an inner surface 73g and the sensor base 72 and the pressure sensor portion 71 and including a rubber portion 75 that forms, on an outer surface, at least a region that comes into contact with a living body and that allows pressure from a wrist 100 to transfer to the pressure sensor portion 71 side; and a soft portion 74 disposed in the gap portion 79 at least between the rubber portion 75 and the pressure sensor portion 71, the soft portion 74 having a lower hardness than the rubber portion 75 and allowing pressure from the rubber portion 75 to transfer to the pressure sensor portion 71.
