PROBLEM TO BE SOLVED: To provide a semiconductor device or the like capable of measuring a rest power source current measured in a short time. SOLUTION: A pad 41 to which the first power source potential is supplied, and a pad 42 connected with one end of an external capacitor 3 are connected to the other end of the capacitor 3. This device is provided with a pad 43 to which the second power source potential is supplied, a pad 44 input with an input signal, the first power source potential supply line 21 connected to the pad 41, and the second power source potential supply line 22 connected to the pad 43. The device is also provided with a control circuit 31 for outputting a control signal in response to a test signal, an inverter 32 for inverting the control signal to be output, an inverter 33 for inverting an output signal of the inverter 32 to be output, and an analog switch 34 brought into off condition when the signal output from the inverter 33 is a high level and when the signal output from the inverter 32 is a low level, and turned on when the signal output from the inverter 33 is a low level and when the signal output from the inverter 32 is a high level.
