Abstract
A power module and a power converter device including the power module include: two base plates with their main surfaces facing each other; a semiconductor circuit unit disposed between the two base plates; a connecting member that is connected to the two base plates and forms a housing region in which the semiconductor circuit unit is housed; and an insulating member that is placed between the base plate and the semiconductor circuit unit and secures electrical insulation of the base plate and the semiconductor circuit unit. A rigidity or thickness of the connecting member is less than a rigidity or thickness of the base plate.
