In a voltage rising/falling type switching regulator including a voltage rising/falling part and a control part, the voltage rising/falling part includes a switching transistor for voltage falling, a rectifier element for voltage falling, a switching transistor for voltage rising, and a rectifier element for voltage rising, the control part is arranged so that the switching transistor for voltage rising and the switching transistor for voltage falling are synchronized at a time of shifting from voltage rising operation to voltage falling operation and/or at a time of shifting from voltage falling operation to voltage rising operation, to perform voltage rising/falling operation in which each switching transistor is turned on in a 50% duty cycle.
