PROBLEM TO BE SOLVED: To provide an internal voltage generator for a semiconductor device capable of outputting a constant voltage regardless of change of a supply voltage. SOLUTION: The internal voltage generator includes: a current mirror unit 201 which has a first transistor P3 connected between the supply voltage and a first node (a), a second transistor N2 connected between the first node and a second node (c), a third transistor P4 connected between the supply voltage and a third node (b) and a fifth transistor N3 connected between the second node and the ground, and in which common gates of the first and third transistors are connected to the first node; a first driver 202 controlled by output signals from the first and second nodes of the current mirror unit; a second driver controlled by the output signal of the first driver; and a voltage divider 204 connected between the output node of the second driver and the ground.
