CARD TYPE ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a card type electronic apparatus having simple and inexpen sive constitution and to which more effective antistatic measures are taken. SOLUTION: Antistatic patterns GL, GL, etc., arranged on one face 20A of a base board 20 and electrolytic casting pattern CP, CP, etc., arranged on the other face 20B of the base board 20 are arranged zigzag on the end face of the base board 20. In the thickness structure of the card, a distance da between the antistatic patterns GL, GL, etc., and the surface of a coating layer 30 is set to be shorter than a distance db between the electrolytic casting pattern CP, CP, etc., and the surface of a card case 10.
