Abstract
A compact reactor with excellent productivity and heat dissipation is provided. Reactorα includes a coil formed by spirally winding a wireand a magnetic corehaving an inside core portion inserted into the coil and an outside core portioncoupled to the inside core portion. These core portions form a closed magnetic circuit. The coil is covered with an inside resin portionon the outer circumference thereof to form a coil molded unitα with its shape being held. The outer circumference of a combination unitof the coil molded unitα and the magnetic coreis covered with an outside resin portionα. Reactorα does not have a case and is thus compact. A surface of the outside core portionon the installation side (core installation surface) is exposed form the outside resin portionα and is in direct contact with a fixed object, thereby achieving excellent heat dissipation. The provision of the coil molded unitα facilitates the handling of the coil during assembly of reactorα, thereby achieving good productivity.
