Card-typed electronic apparatus having a flat card case housing a plurality of electronic parts

A card-type electronic apparatus comprising:

• a flat card case;
• and
• a circuit module housed in the card case, the circuit module comprising:
• a circuit substrate having a first surface and a second surface positioned on the side opposite to the first surface, at least one first electronic part mounted on the first surface of the circuit substrate and at least one second electronic part mounted on the second surface of the circuit substrate, the first electronic part having the greatest height dimension on the first surface and the second electronic part having the greatest height dimension on the second surface being placed in an offset manner from each other without facing each other with the circuit substrate interpolated in between, the circuit substrate being inclined along the thickness direction of the card case so that the inclined structure allows the first electronic part having the greatest height dimension and the second electronic part having the greatest height dimension to be shifted in an approaching direction with each other along the thickness direction of the card case.

A card-type electronic apparatus comprising:

• a flat card case having an opening;
• and
• a circuit module housed in the card case, the circuit module comprising:
• a circuit substrate having a first surface on which a power-apply terminal that is exposed to the opening is placed, a second surface positioned on the side opposite to the first surface, and an electronic part that is mounted at least on the second surface of the circuit substrate and that is electrically connected to the power-apply terminal, the circuit substrate being provided with a first mount area in which the power-apply terminal is positioned and a second mount area in which the electronic part is placed, the first mount area and the second mount area being offset from each other without overlapping with each other on the circuit substrate, as well as being shifted from each other along the thickness direction of the card case.
