<p>A reactor (1) includes a central core (2), a coil (3) provided around the central core (2), a U-shaped core (4) which has an open side and covers all but a portion of the outer peripheral surface of the coil, a top core (5) that covers the upper ends of the central core (2) and the coil (3), and a bottom core (6) that covers the lower ends of the central core (2) and the coil (3). In the reactor (1), a portion (3a) of the outer peripheral surface of the coil (3) that is positioned on the open side of the U-shaped core (4), an open end portion (4a) of the U-shaped core (4), one side portion (5a) of the top core (5), and one side portion (6a) of the bottom core (6) adjoin a cooling member (9).</p> |
