Abstract
Abstract A method for producing an electronic card by printing an electroconductive pattern and a first electrode surface of a battery on a first cover sheet, applying a battery activator onto the first electrode surface, resting an electrolyte-impregnated separator onto the first electrode surface, fixing an IC chip to the electroconductive pattern in a predetermined position, printing a second electrode surface of the battery on a second cover sheet, applying a battery activator onto the second electrode surface, and lapping and sticking the first and second cover sheets together and cutting them into a predetermined size.
