摘要:
A boosting transformer for a high-frequency heating device includes an insulation member (25), and a primary winding (20) and a secondary winding (21) formed at the insulation member (25) and mutually isolated by the insulation member (25), each winding having a width (W1, W2) and a thickness as measured when the winding is stacked (T1, T2), the width (W1, W2) being smaller than the thickness (T1, T2). 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 device. Thus the boosting transformer can be attached to the high-frequency heating device at a location less restrictively and such designing can be facilitated.
