A reactor is composed of a coil and a core placed in the inside area and outer peripheral area of the coil in a container. The core is composed of magnetic powder, non-magnetic powder, and resin. The nom-magnetic powder is composed of main component powder and low elastic modulus powder. The main component powder as a main component of the non-magnetic powder is made of one or more kinds of powder of a heat conductivity which is larger than that of the resin. The low elastic modulus powder is made of one or more kinds of powder of an elastic modulus which is smaller than that of the powder forming the main component powder.
