Abstract
This semiconductor device includes: a first metal plate; a plurality of semiconductor elements mounted on the first metal plate; a spacer that is connected to a surface on the opposite side to the surface where the plurality of semiconductor elements are mounted on the first metal plate; a second metal plate that is connected to a surface on the opposite side to the surface where the spacer is connected to the semiconductor elements; and an encapsulating resin between the first plate and the second plate that seals the plurality of semiconductor elements. Stress due to contraction that occurs in the encapsulating resin between the plurality of semiconductor elements is relaxed to a greater extent than stress due to contraction that occurs in the encapsulating resin in the locations other than the location between the plurality of semiconductor devices.
