Abstract: A transformer includes a silicon substrate, a plurality of metal layers and a plurality of insulating layers laminated on the silicon substrate, a bottom winding of a metal contacting a first metal layer and a second metal layer of the plurality of metal layers, a first insulating layer on the bottom winding, a core on the first insulating layer, a second insulating layer on the core, a top winding of the metal that extends around the core and a portion of the second insulating layer, and a third insulating layer on the top winding. At least one of the top winding and the bottom winding is thicker than each of the plurality of metal layers.

Abstract: A package board that includes an inductor layer having: a first magnetic layer including first magnetic particles and a resin; an inductor wiring that functions as an inductor in the first magnetic layer; and a second magnetic layer on at least one surface of the first magnetic layer, including second magnetic particles that are higher in average flatness than the first magnetic particles and a resin, the second magnetic particles having a shape where the dimension in a direction along the main surface of the second magnetic layer is longer than the dimension in the thickness direction of the second magnetic layer.

Abstract: A magnetic sensor includes a substrate, and a magneto-resistive element portion which is provided on the substrate and has a predetermined magneto-sensitive direction, and in which a bias magnetic field is applied in a direction orthogonal or substantially orthogonal to the magneto-sensitive direction. The magneto-resistive element portion includes a magnetic layer having a negative magneto-striction constant, and stress-induced anisotropy of the magnetic layer develops in a direction parallel or substantially parallel to the direction of the bias magnetic field in response to a tensile stress act on the substrate in a direction parallel or substantially parallel to the magneto-sensitive direction.
