Abstract: A heat-transfer connector 1 comprises a heat-collection side connector half 10, a heat-radiation side connector half 20 and comb-like contacts 25. The heat-collection side connector half 10, which is made of a metal, includes a concave receptive part 10a that extends in a right and left direction while the heat-radiation side connector half 20, which is also made of a metal, includes a convex insert part 20a that extends also in the right and left direction. The comb-like contacts 25 are provided along the front and rear walls of the insert part 20a, respectively, and each of the comb-like contacts 25 protrudes a little in the front and rear direction in a cross-sectional view. When these two connector halves, which are detachable, are connected with each other, heat can be conducted through the comb-like contacts 25, which are in solid contact with and between the two connector halves.
