A heat pipe includes a casing, a main wick structure received in the casing, an auxiliary wick structure received in the main wick structure, and a working fluid contained in the casing. The main wick structure is attached to an inner surface of the casing. An inner peripheral surface of the main wick structure and an outer peripheral surface of the auxiliary wick structure cooperatively define a vapor channel. The auxiliary wick structure is hollow, and extends along a longitudinal direction of the casing. A liquid channel is defined in the auxiliary wick structure. Two ends of the auxiliary wick structure are both fixed on the two ends of the casing. The working fluid is saturated in the main wick structure and the auxiliary wick structure.
