Abstract: An electric vehicle includes an electrical power converter including a case that has electrical conductivity, a cable that connects the electrical power converter and a battery, a high voltage connector that is provided at an end portion of the cable, and that is detachably mountable to the electrical power converter, a resin cover that is fixed to the case, and that protects the cable, a bracket that is fixed to the case, and that fixes the electrical power converter to a vehicle body of the electric vehicle, a metal plate that conducts with the vehicle body via the case and the bracket, and that is fixed on the resin cover, and a ground line that links the high voltage connector and the metal plate.

Abstract: A connector fixing structure includes: a device case including a wall portion in which an attachment hole is provided; and a connector including a housing fixed to the device case, the housing including an insertion portion inserted in the attachment hole, and a shell covering the housing from the outer side. At a part of the wall portion, the part being located around the attachment hole, a projection portion that projects toward one side in an axis direction of the attachment hole from the wall portion is provided. The projection portion includes a lateral portion on one end side in a lateral direction orthogonal to the axis direction. The shell includes a lateral cover portion that covers the lateral portion.

Abstract: A capacitor module includes a plurality of rounded rectangular prism-shaped capacitor elements and a case housing the capacitor elements. The two capacitor elements are disposed in parallel in the case such that respective first side surfaces of the capacitor elements face each other. The case houses the capacitor elements such that second side surfaces of the capacitor elements face a case inner bottom surface of the case. The second side surface is adjoining the first side surface. The case includes at least one of a protrusion or a hole on the side of a case outer bottom surface of the case at an element boundary portion sandwiched between two rounded corners. The round corners are each provided at a boundary between the first side surface and the second side surface.
