Zusammenfassung:This transformer chip includes an element insulating layer and a high-voltage coil and a low-voltage coil embedded in the element insulating layer. The high-voltage coil includes a first end face facing the low-voltage coil side in the z-direction, a second end face opposite the first end face, and a first side face. The element insulating layer includes a third insulating layer, a second insulating layer laminated on the third insulating layer and having a higher relative dielectric constant than the third insulating layer, and a first insulating layer laminated on the second insulating layer and having a lower relative dielectric constant than the second insulating layer. The high-voltage coil is provided within the first insulating layer with the first end face in contact with the second insulating layer.
