【Task】 To provide an IC card equipped with a battery having a new configuration having sufficient power generation capability and capable of supplying stable power. Also, to provide a new IC card that has a low environmental impact and low cost of recycling. [Solution] In an IC card equipped with an electronic device including an IC chip and a battery that provides electric energy necessary for the electronic device to operate, an acid in which the first electrode 1 is disposed as a power generation unit as the built-in battery. The medium 2 and the basic medium 4 on which the second electrode 3 is disposed are provided, and the acidic medium 2 and the basic medium 4 are adjacent to or close to each other, and at least the acidic medium 2 and the basic medium 4 are included. A battery containing a reactive substance is applied. [Selection] Figure 3 |
