Control circuit, control device and clothes

The invention provides a control circuit, a control device and clothes which can restrain complication of equipment structure and are easier to operate. The input connecting part (1) is connected with the mobile power supply (8); an output connection unit (2) connected to the blower fan (91); a switching unit (3) that is electrically positioned between the input connection unit (1) and the output connection unit (2), switches between a closed state in which the input connection unit (1) and the output connection unit (2) are connected and an open state in which the input connection unit (1) and the output connection unit (2) are disconnected, and outputs an operation unit (4) that outputs an operation signal (Os); and a control unit (5) for controlling the switching unit (3), the control unit (5) switching the switching unit (3) to an open state when a non-operating state in which the switching unit (3) is in the closed state and the blower fan (91) is not operating continues for a predetermined time, and swi
