1. A current detecting device comprising:
a bus bar;
a fastening member for fastening an external member to the bus bar:
a chassis that holds the bus bar and the fastening member in a mutual contact; and
a magnetic sensor disposed to face the bus bar, the magnetic sensor being capable of detecting a magnetic field generated when a current under measurement flows through the bus bar; wherein:
the external member is an external conductor that conducts current through the bus bar,
the chassis has a molded body made of resin material,
the bus bar has a fastening terminal portion at an end of the bus bar,
the fastening terminal portion has a connection surface and an anchor portion,
when the fastening terminal portion is viewed from the connection surface side, the anchor portion is disposed on the back side of the connection surface, and the anchor portion has an embedded surface facing the connection surface side,
the connection surface is exposed from a surface of the molded body so that it can come into contact with the external member, and
the embedded surface of the anchor portion is embedded in the molded body.
