PROBLEM TO BE SOLVED: To provide a heating/heat insulating device of a circuit which can appropriately heat only the required region of a circuit by a relatively simple structure. SOLUTION: On a printed wiring board 5 mounting a plurality of circuits 3-1, 3-2 as parts required to heat, a plurality of heating resistors 1-1 to 1-6 disposed near around each of circuits 3-1, 3-2 flush with a face mounting these circuits, temperature sensors 2-1, 2-2 disposed respectively on each of the circuits 3-1, 3-2 and a CPU (controller) 4 which monitors temperature information from the temperature sensors 2-1, 2-2 and controls to enable the plurality of heating resistors 1-1 to 1-6 respectively independently.
