PROBLEM TO BE SOLVED: To provide a flat-plate-type heat pipe assuring good manufacturability and easy layout. SOLUTION: The flat-plate-type heat pipe 2 is structured so that a working fluid of condensing type to convey heat as an evaporative latent heat is encapsulated in a container 6 in a flat plate shape, and includes a container upper part 6A and a container lower part 6B joined with each other in air-tight condition for forming the container 6, wherein a through hole 6E is formed in the container lower part 6B, and the contour of the container upper part 6A has a runoff groove 11 in such a form as retreating toward the inside of the container 6 from the outside line of the container 6 in the neighbourhood of the through hole 6E and following the peripheral part of the through hole 6E, and the container upper part 6A is joined with the container lower part 6B at the contour part 6C.
