## Abstract

An electrical connection unit includes an electronic component including a first terminal, an insulating base member including a plate-shaped or sheet-shaped flat surface portion including a surface facing the electronic component, and a first bus bar supported by the flat surface portion, electrically connected to the electronic component, and including a first plate portion and a first bent portion, in which the first plate portion includes a first connection portion electrically connected to the first terminal, and the first bent portion is bent from the first plate portion in a direction intersecting the surface at a position aligned with the first connection portion.

## Claims

### Claim 1

An electrical connection unit comprising:
an electronic component including a first terminal;
an insulating base member including a flat surface portion having a plate shape or a sheet shape and including a surface facing the electronic component; and
a first bus bar supported by the flat surface portion, electrically connected to the electronic component, and including a first plate portion and a first bent portion, wherein the first plate portion includes a first connection portion electrically connected to the first terminal, and
the first bent portion is bent from the first plate portion in a direction intersecting the surface at a position aligned with the first connection portion.

### Claim 2 (depends on 1)

The electrical connection unit according to claim 1, wherein
in a case where a thickness direction of the flat surface portion is a first direction, the first bent portion extends in the first direction.

### Claim 3 (depends on 1)

The electrical connection unit according to claim 1, wherein
the first bus bar further includes a second bent portion bent from the first plate portion in the direction intersecting the surface at the position aligned with the first connection portion, and
the second bent portion is directed in a direction intersecting a direction in which the first bent portion is directed.

### Claim 4 (depends on 3)

The electrical connection unit according to claim 3, further comprising:
a connection component including a first portion fastened to the first terminal and a second portion fastened to the first connection portion, wherein
the second bent portion is aligned with the connection component in a second direction along the flat surface portion, and
the first bent portion is aligned with the connection component in a third direction intersecting the second direction along the flat surface portion.

### Claim 5 (depends on 3)

The electrical connection unit according to claim 3, further comprising:
a second bus bar supported by the flat surface portion, electrically connected to the electronic component, and including a second plate portion, a third bent portion, and a fourth bent portion, wherein
the electronic component further includes a second terminal, and
the second plate portion includes a second connection portion electrically connected to the second terminal,
the third bent portion is bent from the second plate portion in a direction intersecting the surface at a position aligned with the second connection portion, and
the fourth bent portion is bent from the second plate portion in a direction intersecting the surface and is directed in a direction intersecting a direction in which the third bent portion is directed, at a position aligned with the second connection portion.
