<P>PROBLEM TO BE SOLVED: To provide a card-type electronic apparatus whose outer appearance quality can be enhanced, while reducing the manufacturing cost of a multilayer printed wiring board. <P>SOLUTION: The card type electronic apparatus comprises the multilayer printed wiring board (2) and a case (3) for housing the multilayer printed wiring board. The multilayer printed wiring board is made by alternately laminating a plurality of insulation layers (5a, 5b, 5c) and a plurality of conductor layers (6a, 6b, 6c). One face (4a) of the multilayer printed wiring board along the laminating direction is formed of the insulation layers only, and at least part of this face is exposed out of the case through an opening of the case. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
