<p>Provided is a reactor which exhibits excellent productivity. A reactor (1) comprises an annular magnetic core (11), a molded coil (12A) arranged on the outer circumference of the magnetic core (11), and an outer resin portion (13) covering the outer circumference of an assembly (10) of the magnetic core (11) and the molded coil (12A). A magnetic core (2) is formed annularly by combining a plurality of core pieces and covered with the outer resin portion (13) so that the magnetic core is fixed annularly with no adhesive interposed therebetween. The molded coil (12A) comprises a coil (12) which is formed by winding a wire (12w) spirally, and an inner resin portion (12c) which holds the coil (12) in compressed state. Since a bonding process is not required because adhesive is not used for forming the magnetic core (11), and since the reactor (1) is not required to be formed while compressing the coil (12) because the molded coil (12A) is used, the reactor (1) exhibits excellent productivity.</p> |
