The circuit module is provided with 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. Here, 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 are placed in an offset manner from each other without facing each other with the circuit substrate interpolated in between. Moreover, the circuit substrate is provided with a step portion for allowing 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 to be shifted in an approaching direction with each other along the thickness direction of the card case.
