ABSTRACT:
A current sensor includes a busbar, a case, a connector, and a bare chip having a current detection circuit. The busbar has a crimp terminal at one end, a ring terminal at the other end, and a shunt resistor welded between the crimp and ring terminals. The shunt resistor is encapsulated in the case, and the busbar has an electrode exposed to a sealed inner room of the case. The connector has a connector body unitary with the case and has a connector terminal that is exposed to the inner room at one end and exposed to an outside of the connector body at the other end. The bare chip is arranged in the inner room of the case and wire-bonded to each of the busbar and the connector terminal.
