PROBLEM TO BE SOLVED: To provide a reactor capable of efficiently filling sealing resin at excellent productivity.SOLUTION: A reactor 1A comprises a coil 2; a magnetic core 3 on which the coil 2 is arranged; and a cylindrical case 4A with a bottom for housing an assembly 10 of the coil 2 and the magnetic core 3. A resin introduction path 4r for filling sealing resin 100 coating an outer periphery of the assembly 10 from a bottom side of the case 4A toward an opening side of the case 4A is provided on a side wall 41 of the case 4A. The sealing resin passing through the resin introduction path 4r is compulsorily introduced to the bottom of the case 4A, and filled from the bottom toward the opening while releasing gas in the case 4A. Therefore, in the reactor 1A, (1) the sealing resin can be continuously supplied regardless of viscosity and a filling time can be shortened, (2) entrainment of air bubbles can be reduced to omit a deaeration process, and (3) there is no need for separately removing an introducing cylinder, and so productivity is excellent. |
