1. Electric equipment comprising:

  • a reactor including a pair of winding parts, the winding parts including winding axes on a same virtual plane;

    a bus bar electrically connecting the winding parts and a switching element;

    a switching substrate supporting the switching element; and

    an electric current sensor configured to detect electric current flowing the bus bar,wherein the electric current sensor includes;

    a detection element;

    an annular core having a gap for providing the detection element; and

    a sensor substrate connecting the detection element and a wiring line, and configured to output a signal indicative of an electric current value,the switching substrate is provided along the winding axes, and a part of the switching substrate is overlapped with the reactor, as viewed in a direction perpendicular to the virtual plane;

    the electric current sensor is shifted from the reactor in a direction of the winding axes;

    the sensor substrate is provided in parallel to the virtual plane;

    the bus bar includes a first plate part and a second plate part;

    at least a part of the first plate part is overlapped with the switching substrate as viewed in a direction perpendicular to the virtual plane, and the first plate part extends in parallel to the virtual plane; and

    the second plate part extends from the first plate part toward the switching substrate, as viewed in a direction parallel to the virtual plane.
