Electrical connection unit

An electrical connection unit comprising:

• a first electronic component that includes a component body, a first terminal, and a second terminal;
• a first connection component that is connected to the first terminal of the first electronic component;
• a first routing member that, when a direction in which the first terminal and the second terminal are adjacent to each other is defined as a first direction, a direction intersecting the first direction and in which the component body and the first connection component are adjacent to each other is defined as a second direction, and a direction intersecting the first direction and the second direction is defined as a third direction, includes a first plate portion along the first direction and the second direction, the first plate portion being disposed on a first side in the third direction with respect to the first electronic component and overlapping at least one of the first electronic component or the first connection component when viewed from the third direction;
• and
• a second routing member that includes a second plate portion along the first direction and the second direction, the second plate portion being disposed on a second side opposite to the first side in the third direction with respect to the first electronic component and overlapping at least one of the first electronic component or the first connection component when viewed from the third direction, wherein between the plate thickness of the second plate portion and the plate thickness of the first plate portion, a smaller plate thickness is equal to or larger than half of a larger plate thickness.
