CURRENT SENSOR

PROBLEM TO BE SOLVED: To provide a small current sensor with stable detection accuracy. SOLUTION: The current sensor 1 comprises a bus bar 2 made of a conductor and a U-shaped conductor part 23, and a Hall element 31 for magnetically detecting current flowing in the bus bar 2. With a semiconductor package 3 formed with a Hall element 31, a processing circuit, and a connecting terminal 34 to the outside by molding resin material arranged to position the Hall element 31 inside the conductor part 23 of the bus bar 2, the bus bar 2 and semiconductor package 3 are integrally formed by molding resin material to expose both ends of the bus bar 2.
