A heat pipe ( 1 ) includes a shell ( 20 ), a protective layer ( 10 ) formed on an outer surface of the shell, a wick ( 30 ) and a hydrophilic layer ( 40 ) sequentially formed on an inner surface of the shell and a working fluid contained in the shell. Due to the hydrophilic layer formed on the wick of the heat pipe, the capillarity of the wick is enhanced. Thus, the working fluid is driven to flow from a condenser section of the heat pipe back to an evaporator section of the heat pipe more rapidly. In addition, the protective layer on the outer surface of the shell maintains the degree of vacuum within the heat pipe in a desired range. Thus, the stability and working lifetime of the heat pipe are improved. A method for making the above-described heat pipe is also provided.
