摘要： Provided is a reactor and a reactor component that can prevent cracking of a resin portion that is interposed between a coil and an internal core portion. The reactor includes a coil 10 and a core that includes an internal core portion 22 and a couple core portion 24. The coil 10 is formed by helically winding a wire. The internal core portion 22 is disposed inside the coil and forms a part of a closed magnetic path. The couple core portion 24 is joined to the internal core portion 22 and forms the remaining part of the closed magnetic path. The reactor includes a resin portion (internal resin portion 30) including a region that is interposed between the coil 10 and the internal core portion 22, and a cushioning member 70 that is interposed between the resin portion and the internal core portion 22 and that does not cover the couple core portion 24. It is preferable that the material of the cushioning member 70 has a Young's modulus that is smaller than a resin material of the resin portion.

摘要： A compact reactor with excellent productivity and heat dissipation is provided. Reactor 1α includes a coil formed by spirally winding a wire 2w and a magnetic core 3 having an inside core portion inserted into the coil and an outside core portion 32 coupled to the inside core portion. These core portions form a closed magnetic circuit. The coil is covered with an inside resin portion 4 on the outer circumference thereof to form a coil molded unit 20α with its shape being held. The outer circumference of a combination unit 10 of the coil molded unit 20α and the magnetic core 3 is covered with an outside resin portion 5α. Reactor 1α does not have a case and is thus compact. A surface of the outside core portion 32 on the installation side (core installation surface 32d) is exposed form the outside resin portion 5α and is in direct contact with a fixed object, thereby achieving excellent heat dissipation. The provision of the coil molded unit 20α facilitates the handling of the coil during assembly of reactor 1α, thereby achieving good productivity.
