Abstract
It is an object of the present invention to provide a switch element and a load driving apparatus capable of suppressing a characteristic change of an on-resistance without lowering an off-breakdown voltage. The switching element includes a control electrode, an active element region, and an inactive element region, and the active element region and the inactive element region are formed adjacent to each other on the control electrode. Alternatively, in the load driving apparatus including a current driving switch element and a current detecting switch element that is connected in parallel to the load driving switch element and that detects an energization current of the load driving switch element, the current detecting switch element includes at least a control electrode, an active element region, and an inactive element region, and the active element region and the inactive element region are formed adjacent to each other on the control electrode.
