A first switching element and a second switching element are arranged side by side in a first direction. An output bus bar is disposed to extend in the first direction. The first switching element and the second switching element are disposed to be embedded in a molded portion. The output bus bar includes an embedded portion embedded in the molded portion, a first exposed portion exposed from the molded portion on one side of the switching element set in the first direction, and a second exposed portion exposed from the molded portion on another side of the switching element set in the first direction.

Switching element unit and switching element module for use in an inverter circuit

A connection terminal unit that can be appropriately connected to terminal connection portions of a semiconductor module including a semiconductor element and that can reduce a projection area when seen in a direction orthogonal to a direction along a chip surface is realized. Connection terminal unit includes plurality of connection terminals facing and connected to plurality of terminal connection portions of semiconductor module, and terminal mold portion holding connection terminals. Terminal mold portion has abutment portion that abuts against semiconductor module or base material holding semiconductor module. Abutment portion has vertical abutment portion that abuts against semiconductor module or base material from vertical direction that is a direction in which connection terminals face terminal connection portions, and side abutment portion that abuts against semiconductor module or base material from at least two directions that are different from each other and intersect with vertical direction.

Connection terminal unit

In an inverter module () including a plurality of switching elements (), a positive-polarity bus bar (), a negative-polarity bus bar (), and a plurality of output bus bars (, and), the plurality of output bus bars (, and) are disposed in a first direction (D) in which upper-stage-side switching elements (U) and lower-stage-side switching elements (L) are placed side by side, and the positive-polarity bus bar () and the negative-polarity bus bar () are disposed in a second direction (D) intersecting the first direction (D).
