The refrigerator includes the following parts. A heat-insulating main body has openings in a front side. A divider divides inside of the heat-insulating main body into side by side so as to form a first storage compartment and a second storage compartment having a width smaller than a width of the first storage compartment. The first door turns to open and close at the first storage compartment, and has a vertical axis that extends in an anterior portion of a side wall of the heat-insulating main body. The second door turns to open and close at the second storage compartment, and has a vertical axis that extends in an anterior portion of a side wall of the heat-insulating main body. A concavity part is vertically provided at a front side of an free end of the first door.
