PROBLEM TO BE SOLVED: To provide a pressure-sensitive sensor and a manufacturing method therefor with which it is possible to stably measure applied pressure while taking advantage of the flexibility of cloth, and which can be made to a suitable size for measuring over a wide range of pressure distribution without being subjected to facility size restrictions as for a plating facility and is constituted to achieve high productivity while suppressing material costs.SOLUTION: A pressure-sensitive sensor 1 comprises: a plurality of first electrode cloths 3 disposed at first intervals on the first principal surface of a conductive cloth 2； and a plurality of second electrode cloths 4 disposed at second intervals on the second principal surface of the conductive cloth 2 in a direction crossing the first electrode cloths 3. An intersecting region V1 of the first electrode cloths 3 with the second electrode cloths 4 is formed in a matrix arrangement, with a coating of first conductive particles 11 applied to the conductive cloth 2 and a coating of second conductive particles 12 having higher electrical conductivity than the first conductive particles 11 applied to the first electrode cloths 3 and second electrode cloths 4, the first conductive particles 11 being conductive carbon black.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】布の柔軟性を活かしつつ安定した加圧力の計測が可能となり、かつ、めっき設備のような設備サイズの制約を受けることなく、広範囲の圧力分布を計測可能なサイズにできるとともに、材料費を抑えつつ生産性が高い構成の感圧センサ及びその製造方法を提供することを目的とする。【解決手段】感圧センサ１は、導電布２の第１主面に第１間隔で配された複数の第１電極布３と、導電布２の第２主面に第１電極布３と交差する方向に第２間隔で配された複数の第２電極布４とを備え、第１電極布３と第２電極布４との交差領域Ｖ１がマトリクス配置で形成され、導電布２に第１導電性粒子１１が塗工されているとともに、第１電極布３と第２電極布４とに第１導電性粒子１１よりも電気伝導率が高い第２導電性粒子１２が塗工されており、第１導電性粒子１１は導電性カーボンブラックである。【選択図】図１
