PROBLEM TO BE SOLVED: To make it possible to suppress generation of sensor malfunction even when compression detection is performed using a pressure sensitive member whose electrical characteristics vary in response to compression.SOLUTION: A pressure sensor for detecting compression includes an installation section installed at a location to be detected. The installation section is divided to include pressure sensitive regions 35 and non-pressure sensitive regions 36. The pressure sensitive region 35 is configured to perform compression detection using a pressure sensitive member whose electrical characteristics vary in response to compression. The non-pressure sensitive region 36 is configured to couple neighboring pressure sensitive regions 35 while interleaving the non- pressure sensitive regions 36 and have flexibility in an arrangement direction of each of the regions 35 and 36.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2017,JPO&INPIT【課題】加圧により電気的特性が変化する感圧部材を用いて加圧検知を行う場合であっても、センサ誤動作の発生を抑制することができるようにする。【解決手段】加圧を検知する圧力センサであって、被検出箇所に装着される装着部分を有して構成され、前記装着部分は、領域分割されて感圧領域35と非感圧領域36とを備えており、前記感圧領域35は、加圧により電気的特性が変化する感圧部材を用いて加圧検知を行うように構成されており、前記非感圧領域36は、当該非感圧領域36を挟んで隣り合う前記感圧領域35同士を連結するとともに、各領域35,36の並び方向に伸縮性を有して構成されている。【選択図】図9
