PROBLEM TO BE SOLVED: To provide a reactor which enables the reduction in a thermal stress applied to a core without increasing the number of manufacturing steps.SOLUTION: A reactor 1 comprises: a coil 2 which generates a magnetic flux when being energized; a core 3 formed from a magnetic powder-mixed resin arranged by mixing a resin with magnetic powder, in which the coil 2 is embedded; and a case 4 in which the coil 2 and the core 3 are enclosed. The linear expansion coefficient of the core 3 is between the linear expansion coefficient of the coil 2 and the linear expansion coefficient of the case 4. |
