Summary:a c a c a c. A power supply unit of an arc discharge device includes a semiconductor module and a radiator fitted onto the semiconductor module . The semiconductor module includes a module casing and common units to retained by the module casing . Each of the common units to has: a ceramic substrate having a circuit surface disposed with a semiconductor element and a radiation surface on a side opposite to the circuit surface and a package that exposes the radiation surface and seals the circuit surface with heat resistant resin. The radiator is fitted onto the module casing to be thereby brought into abutting contact with all of the radiation surfaces of the common units to
