PROBLEM TO BE SOLVED: To provide an initialization signal generation circuit capable of surely generating initialization signals, even to the various power sources of the different rising speeds of a power supply voltage. SOLUTION: This circuit is provided with plural initialization signal generation parts 11-1 to 11-n for generating the initialization signals of mutually different time widths, when power is supplied to an electronic device loaded with the initialization signal generation circuit and an initialization signal selection part 12 for selecting the initialization signals of one of the initialization signal generation parts 11-1 to 11-n corresponding to the rising speed of the power supply voltage and supplying the selected initialization signals to the circuit (circuit unit for constituting the electronic device) to be the object of initialization.
