Abstract
A bus bar module includes a first bus bar, a second bus bar, and a first magnetoelectric transducer. The second bus bar is placed in parallel to the first bus bar. The first magnetoelectric transducer is placed so as to be opposed to a side surface of the first bus bar. A sectional area of the first bus bar is smaller than a sectional area of the second bus bar in a first section. The first section is a section passing through the first magnetoelectric transducer and perpendicular to an extending direction of the first and second bus bars.

A bus bar module equipped with a current sensor, the bus bar module comprising:
- a first bus bar;
- a second bus bar placed in parallel to the first bus bar;
- and
- a first magnetoelectric transducer placed so as to be opposed to a side surface of the first bus bar, a sectional area of the first bus bar being smaller than a sectional area of the second bus bar in a first section, and the first section being a cross-section passing through the first magnetoelectric transducer and perpendicular to an extending direction of the first and second bus bars, wherein the second bus bar has one of a projection and a ridge on a side surface of the second bus bar facing away from the first bus bar, the projection and ridge being configured to reduce a magnetic field generated by the second bus bar and to shift current away from the first magnetoelectric transducer in a transverse direction, and wherein the transverse direction is a direction parallel to a virtual line that connects a center of the first bus bar and a center of the second bus bar.
