PROBLEM TO BE SOLVED: To provide a current sensor capable of accurately detecting a current by maintaining a positional relationship between a magnetic field collecting core and a magnetic field detection processing unit, and manufacturing method of the same.SOLUTION: The current sensor includes a bus bar 1, a magnetic field collecting core 2, a magnetic field detection processing unit 4 and a maintaining member 5. The bus bar 1 is used for flowing the current. The magnetic field collecting core 2 includes a surrounding section 2a arranged so as to surround a periphery of the bas bar 1, and a notch 2b provided so as to separate a part of the surrounding section 2a, and magnetically collects the magnetic field generated around the periphery of the bus bar 1 by the current flowing in the bas bar 1. The magnetic field detection processing unit 4 is arranged at the notch 2b apart from the surrounding section 2a and detects the magnetic field collected by the magnetic field collecting core 2. The maintaining member 5 is arranged in a region sandwiched by the magnetic field collecting core 2 and the magnetic field detection processing unit 4 in the notch 2b, and brought into contact with both of the magnetic field collecting core 2 and the magnetic field detection processing unit 4. |
