To provide a touch sensor film with improved spark resistance in manufacturing a touch sensor film.SOLUTION: A touch sensor film has a plurality of detection electrodes and a plurality of leader wiring electrically connected with the detection electrodes. The detection electrode is of mesh structure formed from a conductive fine line. Each of the detection electrodes has at least two connection terminals, that is, a first connection terminal arranged at the nearest position to a leader wiring and a second connection terminal arranged at a position most separated from the leader wiring. The leader wiring extends to the second connection terminal through the first connection terminal and is electrically connected with the first connection terminal and the second connection terminal.SELECTED DRAWING: Figure 1 【課題】タッチセンサフィルムの製造時のスパーク耐性を改良したタッチセンサフィルムを提供する。【解決手段】タッチセンサフィルムは、複数の検知電極と、複数の検知電極に電気的に接続する複数の引き出し配線とを有し、検知電極は導電性細線からなるメッシュ構造であり、さらに、複数の検知電極は、それぞれ少なくとも２以上の接続端子を有し、引き出し配線に最も近い位置に配置される第１接続端子と、引き出し配線から最も離間された位置に配置される第２接続端子とを有し、引き出し配線は、第１接続端子を通じて、第２接続端子まで伸延し、第１接続端子および第２接続端子と電気的に接続する。【選択図】図１
