Abstract
A circuit substrate includes resistive films are disposed on the surfaces of lands included in a circuit pattern and these resistive films are used as resistances connected in series to a capacitor. Therefore, the resistances are connected in series without increasing the inductance in the capacitor, and accordingly, a circuit having a small impedance variation with respect to frequency can be obtained. Therefore, it is possible to obtain a power supply circuit and so forth having stable operation and fast response.
