Semiconductor device with a transmitting insulating element

A semiconductor device comprising:

• a conductive support member including a first die pad and a second die pad, which are separated from each other in a first direction orthogonal to a thickness direction and have relatively different potentials from each other;
• a first semiconductor element that is mounted on the first die pad and forms a first circuit together with the first die pad;
• a second semiconductor element that is mounted on the second die pad and forms a second circuit together with the second die pad;
• an insulating element that conducts to the first semiconductor element and the second semiconductor element and insulates the first circuit and the second circuit from each other;
• and
• a sealing resin that covers the first die pad, the second die pad, the first semiconductor element, the second semiconductor element, and the insulating element and insulates the first die pad and the second die pad from each other,
• wherein the first die pad and the second die pad overlap each other when viewed along the first direction,
• wherein when viewed along the thickness direction, a peripheral edge of the first die pad has a first near-angle portion including a first end portion in a second direction orthogonal to both the thickness direction and the first direction, and
• wherein the first near-angle portion is separated from the second die pad in the first direction toward the first end portion in the second direction.
