Abstract
According to the present invention, a switching element includes a substrate, a first gate pad formed on the substrate, a second gate pad formed on the substrate, a first resistor portion formed on the substrate, the first resistor portion connecting the first gate pad and the second gate pad to each other, and a cell region formed on the substrate and connected to the first gate pad. Thus, measurement of the gate resistance value and selection from gate resistances of the switching element can be performed after the completion of the gate-resistor-incorporating-type switching element.
