PROBLEM TO BE SOLVED: To provide an inexpensive circuit unit which can electrically connect an electric circuit and a signal circuit with simple constitution in short time. SOLUTION: A circuit unit l is formed of a circuit 10 formed by plural long metallic boards and a resin supporting body 40 supporting the circuit 10. The circuit 10 is provided with an electric circuit 20 formed by the metallic board of comparatively thick width and a signal circuit 30 formed by a metallic board which is thinner than the electric circuit 20. The electric circuit 20 and the signal circuit 30 are directly solder-connected in respective solder connection parts 21 and 31.
