Abstract
A first intermediate plate C adjacent to a heat receiving plate A and a second intermediate plate D adjacent to the first intermediate plate C are provided so that the slit width of the openings (first opening ) in the first intermediate plate C is wider than that (second opening ) in the second intermediate plate D. In this way, when the first intermediate plate C and the second intermediate D are stacked, a tunnel structure is formed in which the opening dimension L (the opening dimension of the second openings ) of the communicating sections through which the first openings and the second openings communicate with each other is smaller than the length L (the opening dimension of the first openings ) of the tunnel portions (L >L ). Therefore, a heat-generating member with large density of heat generation can be effectively cooled.
