PROBLEM TO BE SOLVED: To provide a refrigerator capable of opening a plurality of doors while simplifying a circuit constitution relating to a PWM signal, and reducing costs. SOLUTION: This refrigerator comprises a main control portion 114 outputting a specific signal indicating a left door on the basis of a door opening signal from a left door opening switch 27a, and the PWM signal having a duty ratio corresponding to the door opening force, a selecting circuit for selecting a path of a left solenoid 37a corresponing to the left door on the basis of the specific signal, and FET outputting a driving signal to the left solenoid on the basis of the PWM signal.
