An iontophoresis patch (12) which outputs an electric current from an energizing device (14) to an external conductor comprises: a donor portion (16) that has a first contact member (34); a reference portion (18) that has a second contact member (38) and is located on the external conductor away from the donor portion (16); and an electrode body (20) that has a first electrode (42, 70, 80, 90) and a second electrode (44) and that extends across the donor portion (16) and the reference portion (18). The electrode body (20) has a single-sided wiring structure in which the first electrode (42, 70, 80, 90) and the second electrode (44) are formed by a conductive ink being printed on one side of a film (28), the printing pattern of the first electrode (42) has a gap area (43, 71, 81, 91) in which the conductive ink is not printed, and the film (28) and the first contact member (34) are transparent. |
