たことを特徴とするクランプセンサ。[Scope of Claim for Utility Model Registration] A pair of shield cases that are separately formed into openable and closable shield cases and are individually housed and fixed via a casting resin material so that a substantially rectangular magnetic circuit can be formed. In a clamp sensor having a magnetic core, the magnetic core on the side that does not have the magnetoelectric conversion means is arranged in an inner case made of a non-magnetic metal material interposed between the magnetic core and the shield case in which the magnetic core is housed. A clamp sensor characterized in that the clamp sensor is fixed through a molding resin material, and the shield cases are formed so that they can be closed by closely contacting each other.
