To provide a touch sensor pattern that can suppress a failure due to a spark during manufacturing of a touch sensor film while maintaining excellent connection reliability with an FPC.SOLUTION: A touch sensor pattern has a plurality of detection electrodes, a plurality of lead wires connected to the plurality of detection electrodes, and a plurality of external connection terminals connected to the plurality of lead wires. The external connection terminal includes a first fine metal wire having a line width narrower than that of the lead wire, and an area per unit length of at least a part of the external connection terminal along an extension direction in plan view is 5.5 times or less the area per unit length of the lead wire in plan view.SELECTED DRAWING: Figure 4 【課題】ＦＰＣとの接続信頼性に優れながらも、タッチセンサフィルムの製造時のスパークによる故障を抑制できるタッチセンサパターンを提供する。【解決手段】タッチセンサパターンは、複数の検知電極と、複数の検知電極に接続する複数の引き出し配線と、複数の引き出し配線に接続する複数の外部接続端子とを有し、外部接続端子は、引き出し配線よりも細い線幅を有する第１金属細線を含み、平面視における外部接続端子の伸長方向に沿った少なくとも一部の単位長さあたりの面積が、平面視における引き出し配線の単位長さあたりの面積の５．５倍以下である。【選択図】図４
