RADIATOR

PROBLEM TO BE SOLVED: To provide a radiator capable of so dispersing the heat generated from a heat generating body as to prevent the heat from concentrating in a limited scope of a housing. SOLUTION: The radiator 1 is so constituted out of two raw materials 2(2a, 2b) and a raw material 3 having a lower thermal conductivity than the raw materials 2 as to interpose the raw material 3 between the raw materials 2a, 2b. By the radiator 1 having the three-layer structure, the transferring speed of heat in its vertical direction is delayed, and on the other hand, the conduction of much heat is induced in its horizontal direction. As a result, the concentration of the heat generated from a heat generating body 52 to a limited scope in its vertical direction is so suppressed as to disperse the heat in a comparably wide scope 4 of a housing 53 and as to be able to lower the temperature of the heat.
