Capacitive sensor

A capacitive sensor comprising:

• a base material provided with a pattern of a light-transmissive conductive film, wherein
• the light-transmissive conductive film has a structure in which metal nanowires are dispersed in a binder;
• and
• the pattern includes:
• a detection pattern of a plurality of detection electrodes arranged with intervals;
• and
• a plurality of lead-out wirings linearly extending in a first direction from corresponding ones of the plurality of the detection electrodes, wherein
• at least one of the detection electrodes of the detection pattern includes a current path-setting section for elongating a linear path length of a current from the detection electrode toward the lead-out wiring;
• the current path-setting section includes a slit pattern disposed to obstruct the linear path length of the current;
• the current path-setting section includes a plurality of slit patterns having a length of a half or more of the length of the detection electrode and restricting the current path;
• the plurality of the slit patterns are disposed parallel to each other;
• at least a part of the plurality of the slit patterns inward extends from the end of the detection electrode;
• and
• adjacent ones of the slit patterns restrict the current path at positions different from each other;
• the current path-setting section includes a wiring path that allows the path of current flowing from the detection electrode toward the lead-out wiring to meander;
• at least one of the detection electrodes including the current path-setting section and the lead-out wiring extending therefrom have a structure in which the metal nanowires are dispersed in a binder and are formed in a detection region;
• the plurality of the detection electrodes are arranged in the first direction;
• a plurality of pair of one of the detection electrodes and one of the lead-out wirings extending from corresponding one of the detection electrodes are formed so as to be separated from each other;
• the plurality of the lead-out wirings in the detection region include an equal-interval region where the lead-out wirings are arrayed with a constant first pitch in a second direction orthogonal to the first direction;
• the plurality of the slit patterns have widths equal to the intervals of the plurality of the lead-out wirings;
• and
• the pitch of the plurality of the slit patterns is equal to the first pitch.
