Abstract
There is a problem that an area of a principal current cell is reduced by an area of a bonding pad wiring layer for a sub-cell. A source electrodeof a current detection cellis electrically connected to a bonding pad wiring layerformed on an interlayer insulating filmvia a wiring layer contact. The bonding pad wiring layeris formed with respect to a source electrodeof a principal current cellso as to cover a part of the source electrodevia the interlayer insulating film. As a result, the source electrodeis miniaturized, and a size of the source electrodeis made substantially equal to a size of the current detection cell. Therefore, the current detection celland the principal current cellare disposed close to each other.
