    摘要: A power module includes: a base plate having a first surface; electrode plate provided at the first surface; a wire connected to a semiconductor chip and the electrode plate; a metal member connected to the electrode plate; a terminal plate; a first resin layer, a connection portion of the wire and the semiconductor chip being disposed inside the first resin layer; and a second resin layer provided on the first resin layer and having a lower elastic modulus than the first resin layer. The terminal plate includes a bonding portion contacting an upper surface of the metal member, a curved portion curved upward from the bonding portion. The curved portion is disposed inside the second resin layer, and a length from the first surface of a lower surface of the bonding portion is greater than a length from the first surface of the connection portion.

    摘要: A power module includes a base plate, a casing, a substrate unit, a terminal plate, a first resin layer, and a second resin layer. The substrate unit includes a substrate fixed on the base plate, a dam part, a semiconductor chip, a metal member, and a wire. The dam part is formed along an edge of the substrate. The wire includes an electrode plate connection portion, and a chip connection portion. The first resin layer is located inward of the dam part. The chip connection portion and the electrode plate connection portion are located inside the first resin layer. The second resin layer is located on the first resin layer. The upper surface of the metal member is located inside the second resin layer. An elastic modulus of the second resin layer is less than that of the first resin layer.
