Abstract
An electric current detector is provided wherein loose arrangement of conductorin openingprovides an air gap between the conductorand plastic packagein openingto prevent close contact of conductorto plastic package. When heat and heat stress are produced in conductorby a large electric current flowing through conductorduring measurement, air gap surely prevents heat and heat stress from traveling to Hall effect sensorand plastic packagewhile a part of heat in conductoris radiated into air in opening. Thus, the loose arrangement of conductorcan restrict or reduce deterioration of electric property in Hall sensorand degradation of mechanical property in plastic packageby heat and heat stress in conductor. Also, the loose arrangement ensures and facilitates attachment of the detectorin position on a surface of a substrate, and enables to maintain conductorat the same level as lead terminalsof the detector.
