In this case, the static electricity generated in the synthetic resin hose is transmitted to the control board via the wiring inside the hose, and in particular, this control board is known to the applicant in Japanese Patent Application No. 62-241622. In the case of an insulated high heat conductive substrate with high insulation resistance between printed patterns, such as the one used in the proposed vacuum cleaner, in which a conductive member is printed on a metal plate such as an aluminum plate via an insulating heat transfer layer, Spontaneous discharge is difficult to occur, and the electric charge is accumulated and becomes high voltage, which is discharged in the air to the electric power supplied with commercial power on the control board [1 pattern (AC power line butter)], and at that time, the circuit elements on the control board are There was a risk of destruction due to high-voltage static discharge. Furthermore, even if the control board is a conventional phenolic printed circuit board, the insulation resistance between the printed patterns is inferior to that of the insulated high heat conductive board, so spontaneous discharge increases. However, the air discharge 1 still occurs. There was a risk of destroying circuit elements.
