PROBLEM TO BE SOLVED: To provide a touch detection sensor which has no dead band and which allows touch detection at any position.SOLUTION: The touch detection sensor comprises: a first conductive sheet 11 a first insulation spacer 15 which is laminated on one face of the first conductive sheet 11, and which has an opening 17 penetrating through a thickness direction a second conductive sheet 14a which is laminated on a face of the first insulation spacer 15 opposite to a face making contact with the first conductive sheet 11 a second insulation spacer 16 which is laminated on the other face of the first conductive sheet 11, and which has an opening 19 penetrating through the thickness direction and a third conductive sheet 14b which is laminated on a face of the second insulation spacer 16 opposite to a face making contact with the first conductive sheet 11. An insulation piece 18 constituting the first insulation spacer 15 overlaps the opening 19 in a lamination direction of the conductive sheets, while an insulation piece 20 constituting the second insulation spacer 16 overlaps the opening 17 in the lamination direction of the conductive sheets.COPYRIGHT: (C)2012,JPO&INPIT【課題】不感帯域のない、いずれの箇所でも接触を検知することのできる接触検知センサを提供することを目的とする。【解決手段】接触検知センサは、第一導電シート11と、第一導電シート11の片面に積層し、且つ、厚み方向に貫通した開口17を有する第一絶縁スペーサ15と、第一絶縁スペーサ15に対して第一導電シート11に接する面と反対側の面に積層した第二導電シート14aと、第一導電シート11の他面に積層し、且つ、厚み方向に貫通した開口19を有する第二絶縁スペーサ16と、第二絶縁スペーサ16に対して第一導電シート11に接する面と反対側の面に積層した第三導電シート14bと、を備え、第一絶縁スペーサ15を構成する絶縁片18は、開口19と導電シートの積層方向に重なり、第二絶縁スペーサ16を構成する絶縁片20は、開口17と導電シートの積層方向に重なる構成である。【選択図】図1
