Abstract: A reactor includes a laminated core formed by laminating soft-magnetic ribbons in a lamination direction. The laminated core has a gap formed across a magnetic path direction in the laminated core. The laminated core also has a flat facing surface that faces the gap and a pair of flat side surfaces that are respectively on opposite sides of the facing surface in the lamination direction. The laminated core further has a pair of first corner curved surfaces that are formed between the facing surface and the pair of side surfaces. Each of the first corner curved surfaces has a width in the lamination direction greater than the thickness of each of the soft-magnetic ribbons. For each of the first corner curved surfaces, a length of the first corner curved surface in the magnetic path direction is greater than the width of the first corner curved surface in the lamination direction.

Abstract: An inverter device includes an inverter housing and an arm switch unit. The inverter housing includes an inverter outer peripheral wall and an inverter fin. The inverter outer peripheral wall has an outer peripheral surface and an inner peripheral surface and extends annularly around an inverter axis. The inverter fin is provided on the outer peripheral surface and extends toward a radially outer side from the outer peripheral surface. Multiple arm switch units are arranged in a circumferential direction and are fixed to the inner peripheral surface. The arm switch unit is a heat generation component that generates heat by energization. Heat transferred to the inner peripheral surface from the arm switch unit is dissipated to the outside from the outer peripheral surface of the inverter outer peripheral wall.
