Abstract
A resistive field plate is arranged in a spiral shape in plan view so as to gradually approach an inner main electrode from an outer main electrode. The plurality of floating layers are arranged radially toward the low potential region around the high potential region in plan view. The resistive field plate is provided on the plurality of floating layers via an interlayer insulating film, and thus has a floating step reflecting a film thickness of each of the plurality of floating layers. That is, the resistive field plate is provided in such a manner that the floating step is repeatedly generated along the lapping direction.
