1. A semiconductor device comprising: a first power supply terminal; a second power supply terminal; an output terminal; at least one first switching element connected between the first power supply terminal and the output terminal; and at least one second switching element connected between the second power supply terminal and the output terminal, wherein
the first power supply terminal includes
a first facing portion disposed at a distance from the second power supply terminal in a first direction and disposed to extend in a second direction crossing the first direction,
a second facing portion disposed at a distance from the second power supply terminal in the second direction and disposed to extend in the first direction, and
a third facing portion disposed at a distance from the second facing portion in the second direction and disposed to extend in the first direction,
the first facing portion and the second facing portion are provided such that, upon application of a current, the current flows through the first facing portion and the second facing portion in a direction opposite to a direction in which the current flows through each of portions in the second power supply terminal that face the first facing portion and the second facing portion, and
the second facing portion and the third facing portion are provided such that, upon application of a current, the current flows through the second facing portion in a direction opposite to a direction in which the current flows through the third facing portion,
the first power supply terminal further includes
a first external connection portion connected to outside, and
a first upright portion extending in the second direction,
one end of the first upright portion in the second direction is connected to one end of the first external connection portion in the first direction,
the other end of the first upright portion in the second direction is connected to one end of the third facing portion in the first direction, and
the other end of the third facing portion in the first direction is connected to one end of the first facing portion in the second direction.
