a main body, having a first accommodation chamber and a second accommodation chamber;
a lid, capable of being opened and closed with respect to the main body;
a cooling mechanism that cools the first accommodation chamber and the second accommodation chamber;
a control part that includes a microcomputer, which controls the cooling mechanism; and
a setting part that includes a setting button, which allows a user to individually make set temperatures of the first accommodation chamber and the second accommodation chamber be set between a highest set temperature and a lowest set temperature respectively, wherein
the control part is configured to set the set temperatures based on an operation of the setting part and control a set temperature difference between the set temperature of the first accommodation chamber and the set temperature of the second accommodation chamber to be within a predetermined value, wherein the user performs an operation to set the set temperature of the first accommodation chamber in the setting part, and when an operation is performed to cause the set temperature difference to exceed a predetermined value, the set temperature of the first accommodation chamber is not changed even if the operation is performed.
