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 coiland a core that includes an internal core portionand a couple core portion. The coilis formed by helically winding a wire. The internal core portionis disposed inside the coil and forms a part of a closed magnetic path. The couple core portionis joined to the internal core portionand forms the remaining part of the closed magnetic path. The reactor includes a resin portion (internal resin portion) including a region that is interposed between the coiland the internal core portion, and a cushioning memberthat is interposed between the resin portion and the internal core portionand that does not cover the couple core portion. It is preferable that the material of the cushioning memberhas a Young's modulus that is smaller than a resin material of the resin portion.
