Abstract: A microwave oven includes a filter unit having choke coils disposed on ground lines, to which low and high voltage units are grounded, and on a power line connected to a controller so as to block high frequency noise. Impedances of the ground and power lines are greatly increased by the choke coils. Accordingly, noise is prevented from being radiated to the outside through the ground lines, and from flowing to the controller through the power line, thus allowing the controller to perform a stable operation.

Abstract: A boosting transformer for a high-frequency heating apparatus includes an insulation member, and a primary winding and a secondary winding formed at the insulation member and mutually isolated by the insulation member, each winding having a width and a thickness as measured when the winding is stacked, the width being smaller than the thickness. As such, the boosting transformer can be reduced in height to readily ensure a distance for insulating locations having therebetween a large potential difference from each other in the transformer's internal structure in designing a structure in which the transformer is attached to a high-frequency heating apparatus. Thus the boosting transformer can be attached to the high-frequency heating apparatus at a location less restrictively and such designing can be facilitated.
