PROBLEM TO BE SOLVED: To provide a sensor module capable of improving protection strength of a surface that comes in contact with a living body, and preventing damage, and a blood pressure measuring device.SOLUTION: A sensor module 63 of a blood pressure measuring device 1 includes: a sensor base 72； a pressure sensor part 71 fixed to the sensor base 72； a sensor head cover 73 that is fixed to the sensor base 72, forms a gap part 79 among an internal surface 73g, the sensor base 72, and the pressure sensor part 71, and includes a rubber part 75 forming at least a region that comes in contact with the living body on an external surface, which can transmit the pressure from a wrist 100 to a pressure sensor part 71 side； and a soft part 74 provided at least between the rubber part 75 and the pressure sensor part 71 in the gap part 79, whose hardness is lower than that of the rubber part 75, and which can transmit the pressure from the rubber part 75 to the pressure sensor part 71.SELECTED DRAWING: Figure 13COPYRIGHT: (C)2020,JPO&INPIT【課題】生体に接触する表面の保護強度を向上し、破損を防止できるセンサモジュール、及び血圧測定装置を提供すること。【解決手段】血圧測定装置１のセンサモジュール６３は、センサベース７２と、センサベース７２に固定された圧力センサ部７１と、センサベース７２に固定されて内表面７３ｇとセンサベース７２及び圧力センサ部７１との間に間隙部７９を形成し、かつ、外面の少なくとも生体に接触する領域を形成する、手首１００からの圧力を圧力センサ部７１側に伝達可能なゴム部７５を有したセンサヘッドカバー７３と、間隙部７９内の、少なくともゴム部７５と圧力センサ部７１との間に設けられ、ゴム部７５よりも硬度が低く、かつ、ゴム部７５からの圧力を圧力センサ部７１に伝達可能な軟質部７４と、を備える。【選択図】 図１３
