Claim 19:
20. The semiconductor module according to claim 19,
wherein the bent portion is provided at two portions on a side closer to the die stage and a side farther from the die stage,
wherein each of the bent portions at two portions of the first lead has a bimetal structure,
wherein a bimetal structure of a first bent portion being a side farther from the die stage among the two bent portions is a structure in which a linear expansion coefficient of an upper side metal is higher than a linear expansion coefficient of a lower side metal, and
wherein a bimetal structure of a second bent portion on a side closer to the die stage among the two bent portions is a structure in which a linear expansion coefficient of an upper side metal is lower than a linear expansion coefficient of a lower side metal.
