<P>PROBLEM TO BE SOLVED: To provide an electronic information storage card and a manufacturing method for it capable of reducing thickness variation for good surface smoothness in a lamination body and improving an appearance, printing performance on the surface, and the like. <P>SOLUTION: In this electronic information storage card, the lamination body is formed when an antenna board 2 formed by mounting an IC chip 2b and an antenna circuit 2c on a board 2a is put to be stuck between adhesion layers 6 and 7, which face each other, of a pair of sheet materials 10 and 20 individually having the adhesion layers 6 and 7 on one side. In the electronic information storage card, a difference between the maximum value and the minimum value of thickness of the adhesion layers 6 and 7 each previously formed on one side to be stuck mutually is 40 μm or less in a pair of sheet material 10 and 20 having the adhesion layers 6 and 7. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
