A cotton candy preparing device (100) is desired which does not operate with a pan portion (201) removed. To provide a cotton candy preparing device (100) that prevents a user from taking some time before getting aware that the device is not operating properly, there is provided a cotton candy preparing device (100) having a pan portion (201) that is fixed on to a main body portion (110) by a locking piece (223), wherein a power supply switch (410) is incorporated in the main body portion (110), wherein the power supply switch (410) has a switch operating rod (411) that enables on and off operations of a circuit, and a locking body (441) that restricts a sliding movement of the switch operating rod (411), and wherein when the pan portion (201) is fixed to the main body portion (100) by the locking piece (223), the locking body (441) is moved by the locking piece (223) to thereby enable the switch operating rod (411) to slide.
