Circuit board unit

摘要

A circuit board unit includes a printed circuit board and a terminal block mounted on the printed circuit board and connecting a power module and an electrical wire together. The terminal block includes a terminal connection part to be directly connected to the power module, and a wire connection part to be connected to the electrical wire. In the printed circuit board, a hole having an orthographic projection area larger than that of the terminal connection part as viewed in plane is formed. The terminal connection part is positioned below or above the hole of the printed circuit board.
