Kind Code:
B2
Abstract:
To provide a reactor excellent in heat dissipation.SOLUTION: In a reactor including a coil having a wound part, a magnetic core having an inner core part placed in the wound part, and an inner inclusion member for ensuring insulation between the wound part and the inner core part, the inner inclusion member includes a thin wall part which is made thin as the inner peripheral surface is recessed, and a thick part thicker than the thin wall part. The inner core part is provided, on the outer peripheral surface facing the inner inclusion member, a core side protrusion having a shape copying the inner peripheral surface shape of the thin wall part. The thickness of the thick part is 0.2-1.0 mm, the thickness of the thick wall part is 1.1-2.5 mm, the inner core part and the inner inclusion member adhere substantially, and there is a clearance at least partially between the inner inclusion member and the wound part.SELECTED DRAWING: Figure 3
