1. A semiconductor device configured for connection to a capacitor, the semiconductor device comprising:
a terminal portion including:
a first external terminal having a front surface and a rear surface opposite to each other, the first external terminal having a first end portion configured for connection to one terminal of the capacitor, the first end portion having a first end at an outer periphery thereof;
a second external terminal having a front surface, the front surface of the second external terminal having a first area located at a periphery thereof and configured for connection to another terminal of the capacitor, and a second area positioned adjacent to and inward of the first area, both the first and second areas extending beyond the first end in a plan view of the semiconductor device, thereby being exposed relative to the first external terminal; and
an insulating sheet disposed between the rear surface of the first external terminal and the front surface of the second external terminal such that the front surface of the second external terminal is exposed from the insulating sheet, and from the first external terminal at the first area in the plan view, wherein,
at the first end portion, the rear surface of the first external terminal is angled relative to the front surface of the second external terminal so that, in a thickness direction of the first external terminal, a distance between the rear surface of the first external terminal and the front surface of the second external terminal increases as the first end is approached,
the first end of the first end portion of the first external terminal extends in a first direction,
the first external terminal further includes a second end portion having a second end and a third end portion having a third end, the second and third end portions being located along respective ones of two sides of the first external terminal in a second direction orthogonal to the first direction,
at each of the second and third end portions, the rear surface of the first external terminal is angled relative to the front surface of the second external terminal so that in the thickness direction, a distance between the rear surface of the first external terminal and the front surface of the second external terminal increases as a corresponding one of the second end or third end is approached,
the second external terminal has two side faces that are parallel to each other in the second direction, and
the side faces of the second external terminal each have a notch respectively provided at the same positions where a corner formed by the first end of the first end portion and the second end of the second end portion and a corner formed by the first end of the first end portion and the third end of the third end portion are located, each notch being recessed inward from each of the side faces of the second external terminal in the plan view.
