Abstract
A semiconductor device includes two first switching elements mounted on a first die pad. Each of the two first switching elements includes a first control electrode connected to a first control lead by a first control connection member. The first control connection member includes a lead connector connected to the first control lead and electrode connectors connected between the lead connector and the first control electrodes of the first switching elements. The electrode connectors are equal in length. Thus, the connection members between the first control lead and the first control electrodes of the first switching elements are equal in length.
