Semiconductor device

A semiconductor device, comprising:

• a transistor section including a source electrode that is provided on a first face of a semiconductor substrate and is electrically connected to a source terminal, a drain electrode that is provided on a second face opposite to the first face in the semiconductor substrate and is electrically connected to a drain terminal, and a gate electrode that is provided between the source electrode and the drain electrode;
• a gate electrode pad that is provided on the first face;
• a gate connection member that electrically connects the gate electrode pad and a gate terminal;
• a gate circuit section that is provided on the first face and is electrically connected between the gate electrode pad and the gate electrode;
• and
• a casing that accommodates the transistor section, the gate electrode pad, and the gate circuit section,
• the gate circuit section including,
• a capacitor,
• a resistive element that is connected to the capacitor in parallel,
• a first connection member that electrically connects one electrode of the capacitor to the gate electrode pad, and
• a second connection member that electrically connects the other electrode of the capacitor to the gate electrode.
