A cooling effect is produced by collision of coolant (10) introduced into coolant introduction chamber (3) with the back face side of heat-generating elements (1) within a first coolant contact chamber (4) by injection from a central nozzle (7). Thereafter in the same way coolant (10) produces a cooling effect in a second coolant contact chamber (5) and third coolant contact chamber (6). Since peripheral nozzles (8) and (9) are formed so as to spread in radial fashion about central nozzle (7) as center, cooling is effected to practically the same level of temperature, so there is no possibility of large tensile heat stress being generated at heat-generating elements (1).
