A heat pipe includes an air tight elongated container and a heat carrier sealed in the container. The elongated container has a flat bottom wall serving as a heat receiving portion and a top wall serving as a heat dissipating portion. A liquid passage for moving condensed heat carrier in a slanted direction and parallel directions with respect to the longitudinal axis by capillary action is provided on the inner wall surfaces of the container. The heat carrier which has been condensed into liquid flows along the liquid passage to be distributed entirely over the bottom wall surface where it efficiently absorbs heat to be evaporated again.
