POWER MODULE, ELECTRIC ENERGY CONVERSION DEVICE, AND METHOD FOR PRODUCING A POWER MODULE

摘要

It is an object of the invention to provide a power module in which the adhesion of a sealing resin is sufficient and which is highly reliable. The power module has the following: an insulating plate (11) in which a pattern of a conductor layer (13) is formed on a ceramic plate; Power semiconductor elements (21, 22) placed on the insulating plate (11); Lead frames (611a, 612a) each in plate form, which connect electrodes of the power semiconductor elements (21, 22) to screw fastening connection areas (611, 612); and a sealing resin region (7) that seals connection regions between the power semiconductor elements (21, 22) and the lead frame (611a, 612a) and regions around the connection regions; wherein in the lead frame (611a, 612a) opening areas (611b, 612b) are formed at positions where each of the lead frames at least partially overlaps in plan view with an area of the insulating plate (11) on which the lead layer (13) is not formed.
