A voltage detection circuit including a voltage input terminal, a voltage dividing circuit, a voltage comparison circuit, an output terminal, a detection voltage adjustment terminal, a voltage-current conversion circuit, and a constant current source. A voltage to be monitored is input to the voltage input terminal. The voltage dividing circuit includes series resistors between the voltage input terminal and a constant voltage terminal. The voltage comparison circuit compares a voltage divided by the voltage dividing circuit with a predetermined voltage. The comparison result is output from the output terminal. An external resistor is connected to the detection voltage adjustment terminal. The voltage-current conversion circuit is provided between the detection voltage adjustment terminal and the voltage dividing circuit. The constant current source is connected between an internal power supply voltage terminal and the detection voltage adjustment terminal.
