When the value of a power supply voltage (VDD) becomes a first threshold value or higher, a first start-up circuit (20) causes a band gap reference circuit (10) to start a stable operation and a first voltage value (VA) is output from the band gap reference circuit (10). When the value of the power supply voltage becomes a second threshold value or higher which is greater than the first threshold, a second start-up circuit (40) turns on a PMOS transistor (MP3) of a voltage dividing circuit (30), and a second voltage value (VB) output from the voltage dividing circuit (30) becomes a value, which is derived by dividing the value of the power supply voltage according to the resistance ratio of resistors (R31, R32). From a voltage comparison circuit (50), a reset level voltage value is output when the second voltage value (VB) is smaller than the first voltage value (VA), and a power-supply voltage level voltage value is output if the second voltage value (VB) becomes the first voltage value (VA) or higher.
