1. A heat transport device having a container with an internal space in which a working fluid is filled, comprising:
an evaporator;
a condenser which is arranged at a position separated from the evaporator; and
an intermediate part arranged between the evaporator and the condenser,
wherein the evaporator causes the working fluid to evaporate,
wherein the condenser causes the working fluid to condense,
wherein at least one main groove which extends continuously from the condenser to the evaporator through the intermediate part is formed in the container,
wherein a part or entirety of main grooves among the at least one main groove is a sloped groove having a sloped groove bottom that, when viewing a cross section along an extending direction of the main groove, slopes from a groove bottom position of a groove portion positioned at the condenser towards a groove bottom position of the groove portion positioned at the evaporator, so as to approach a bottom surface of the heat transport device, and
wherein a portion linking a center position of the condenser and a center position of the evaporator when viewing a cross section along the extending direction of the sloped groove, has an average sloping angle relative to a heat input surface of the container in a range of at least 1 degree and no more than 30 degrees.
