A heat pipe is produced by forming on a container an outwardly projecting tube portion having an interior in communication with the interior of the container for providing a gas retaining portion, injecting a working liquid into the container through an outer end opening of the tube portion, subsequently closing the end opening of the tube portion to thereby form the gas retaining portion on the container, heating the container to evaporate the working liquid to cause the gas retaining portion to retain therein noncondensable gases within the container, thereafter closing a container opening in communication with the gas retaining portion and separating the gas retaining portion from the container for removal. The weight of the container having the gas retaining portion and the combined weight of the heat pipe obtained and the separated gas retaining portion are measured and compared.
