A capillary tube heat pipe and the like are provided, in which is applicable for a case that a heat receiving portion is separated apart from a heat radiating portion, and a sufficient space for connecting the both portions does not exist. This capillary tube heat pipe (1) is provided with two turn portions (a heat receiving portion and a heat radiating portion) (3-1) and (3-2) at the both ends thereof and a straight portion (a heat transfer portion) (5) extending between the both turn portions (3), and has a closed loop structure in which both terminals of a single pipe are communicated. Since the heat transfer portion is made from two straight pipes (7) and (9), the straight portion (5) can be small in size.
