Current sensor device

A current sensor device comprising:

• at least one bus bar that has a front surface and a back surface opposite to the front surface in a thickness direction of the bus bar;
• at least one sensor package that includes a magneto-electric conversion element which detects a current flowing through the bus bar and an external connection terminal which is electrically connected to the magneto-electric conversion element, the at least one sensor package being fixed to the front surface of the bus bar;
• a printed circuit board that is disposed on the sensor package opposite to the bus bar, and electrically connected to the terminal;
• a magnetic shield body that shields the magneto-electric conversion element from an external magnetic field;
• and
• a resin element that integrally holds at least a part of the magnetic shield body and the bus bar fixed to the sensor package.
