Abstract: Object:To provide an FPC integrated capacitance switch and a method of manufacturing the same, which allow an FPC portion to have high electrical reliability when used in a bent manner and to have wiring lines to be densely arranged.Solution:The FPC integrated capacitance switch includes a transparent flexible substrate (1) including a sensor unit (11) and a tail portion (12), a plurality of electrodes (2) formed on a first main surface (1a) of the transparent flexible substrate (1) and in the sensor unit (11), a plurality of first electrode wiring lines (21), a plurality of second electrode wiring lines (22) arranged and formed in parallel in the tail portion (12) and made of a photoresist including conductive particles, an electromagnetic shield (3) formed on a second main surface (1b) of the transparent flexible substrate (1) overlapping in plan view a region including the plurality of electrodes (2), a pair of first electromagnetic shield wiring lines (31), a pair of second electromagnetic shield wiring lines (32) formed in the tail portion (12) to be arranged in plan view outward of a region including the plurality of second electrode wiring lines (22), the second electromagnetic shield wiring lines (32) being made of a photoresist including conductive particles, and an electromagnetic shield mask (33) formed on the second main surface (1b) of the transparent flexible substrate (1) overlapping in plan view the region including the plurality of second electrode wiring lines (22), the electromagnetic shield mask (33) including a light-shielding metal film.
