PROBLEM TO BE SOLVED: To render a conductive thin line constituting a conductive pattern of a touch panel sensor to be less likely visually recognized by an observer.SOLUTION: A touch panel sensor 30 is disposed on a display screen of an image display mechanism and includes a counter face 30a that forms a face opposing to the display screen of the image display mechanism, an opposite face 30b that forms a face on the opposite side to the counter face 30a, and a first electrode 41 and a second electrode 42 spaced in a thickness direction of the touch panel sensor 30. Each of the first electrode 41 and the second electrode 42 has a conductive pattern 50 including a conductive thin line 52 having a first face 52a forming a face on the counter face 30a side, a second face 52b forming a face on the opposite side, in the thickness direction of the touch panel sensor 30 side, to the first face 52a, and a pair of side faces 52c, 52d connecting the first face 52a and the second face 52b. A width of the conductive thin line 52 of the conductive pattern 50 varies to decrease from the second face 52b side to the first face 52a side.SELECTED DRAWING: Figure 6 【課題】タッチパネルセンサの導電性パターンをなす導電性細線が観察者に視認されることを抑制する。【解決手段】タッチパネルセンサ３０は、画像表示機構の表示面上に配置され、画像表示機構の表示面に対向する面をなす対向面３０ａと、対向面３０ａと反対側の面をなす反対面３０ｂと、タッチパネルセンサ３０の厚み方向に離間して配置された第１電極４１及び第２電極４２を有する。第１電極４１及び第２電極４２は、それぞれ、対向面３０ａ側の面をなす第１面５２ａと、タッチパネルセンサ３０の厚み方向に沿って第１面５２ａと反対側の面をなす第２面５２ｂと、第１面５２ａと第２面５２ｂとの間を接続する一対の側面５２ｃ，５２ｄと、を有する導電性細線５２、を含む導電性パターン５０を有する。導電性パターン５０の導電性細線５２の幅は、第２面５２ｂ側から第１面５２ａ側に向けて小さくなるように変化する。【選択図】図６
