Beschreibung
Zusammenfassung:	The utility model aims to provide a heat pipe which can prevent a container from deforming even if the longitudinal direction of the container is approximately parallel to the gravity direction in a cold region, the bottom of the container is heated, and working fluid is frozen, and the heat pipe has excellent heat transfer characteristics. This heat pipe is provided with: a container having a tubular shape for sealing the end surface of one end and the end surface of the other end, and having an inner wall surface on which a groove is formed; a sintered body layer which is provided on the inner wall surface of one end of the container and which is formed by sintering a powder; and a working fluid sealed in the cavity of the container, the sintered body layer has a first sintered portion located on the end surface side of the one end portion, and a second sintered portion that is continuous with the first sintered portion and located on the other end portion side. The average primary particle diameter of the
