A voltage detection circuit includes: a self-bias unit, generating a self-bias voltage based on a reference voltage; and detection units, comparing magnitudes of each voltages as a detection target and a reference voltage, and outputting first to nvoltage detection signals indicating whether the voltage is higher than the reference voltage. Each detection units includes: fifth and sixth transistors, respective drains being connected, and, with respective gates receiving one of the voltages, the fifth and sixth transistors outputting a voltage generated at the respective drains as one of the voltage detection signals; seventh and eighth transistors, respectively supplying a current corresponding to the self-bias voltage to the fifth and sixth transistors. The voltage detection circuit includes a current source transistor, causing an operating current based on a bias voltage received by the gate to flow through the self-bias unit and the detection units.
