PROBLEM TO BE SOLVED: To provide a method of manufacturing a cooling plate capable of disposing a metallic pipe regardless of its length by a sheet of metallic plate, and having high heat exchanging efficiency. SOLUTION: A pipe accommodating groove 21 having a diameter substantially larger than the metallic pipe 3 is formed on one face of a heat transfer plate 2 along a piping line of the metallic pipe 3, the metallic pipe 3 is mounted in the pipe accommodating groove 21 and pressed through a specific pressing means, the pressurized fluid is supplied into the metallic pipe 3 to enlarge the metallic pipe 3 from its inner side, and the metallic pipe 3 is closely attached along an inner peripheral face of the pipe accommodating groove 21 to be integrally installed in the heat transfer plate 2.
