A circuit assembly includes a circuit board including a control circuit for controlling the flow of electric current in a power circuit is integral with the top of a plate-shaped busbar. The circuit assembly includes a circuit board in which both sides are provided with circuit patterns and having a via hole for electrically connecting the circuit patterns to each other, an adhesive sheet is interposed between the busbar and the circuit board and fixes the circuit board to the top of the busbar, a hole filling resin fills the via hole, and a resist layer is formed on at least a side of the circuit board that faces the busbar, covering the via hole filled with the hole filling resin. The adhesive sheet includes a substrate made of an insulating material, and adhesive layers are formed on both sides of the substrate and are sticky at room temperature.
