A semiconductor device which reduces a source resistance and a manufacturing method for the same are provided. The semiconductor device has a nitride based compound semiconductor layer arranged on a substrate, an active region which has an aluminum gallium nitride layer arranged on the nitride based compound semiconductor layer, and a gate electrode, source electrode and drain electrode arranged on the active region. The semiconductor device has gate terminal electrodes, source terminal electrodes and drain terminal electrode connected to the gate electrode, source electrode and drain electrode respectively. The semiconductor device has end face electrodes which are arranged on a side face of the substrate by a side where the source terminal electrode is arranged, and which are connected to the source terminal electrode. The semiconductor device has a projection arranged on the end face electrode which prevents solder used in die bonding from reaching the source terminal electrodes.
