<p><P>PROBLEM TO BE SOLVED: To reduce the thickness of a current sensor, simplify its structure, improve the connection reliability, and construct a circuit structure having the current sensor and a power circuit while maintaining a thin, simple structure. <P>SOLUTION: The current sensor comprises a current detection bus bar 10 having an input terminal section 11 and an output terminal section 12 and a circuit board 30 into which a detection circuit is incorporated, wherein the detection circuit measures a voltage drop between specific measurement points 11p, 12p and outputs a current detection signal. The bus bar 10 and the circuit board 30 are brought together through an insulating layer, while the measurement points 11p, 12p are connected to the detection circuit. Power circuit forming bus bars 22, 24, 25, 26, together with the current detection bus bar 10, and the circuit board 30 are brought together to construct the circuit structure having the current sensor. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
