  • Publication number: 20180137975
    Abstract: A thin film-type inductor includes a body including a support member, a coil disposed. on at least one surface of the support member, and a filler embedding the support member on which the coil is disposed, and an external electrode disposed. on an external surface of the body. An insulating layer is not disposed on an edge portion of the support member and the edge portion is in direct contact with a filler. The insulating layer is only disposed on an upper surface of the coil to conform to a surface of the coil.
