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.
