A composite multi-layer wick structure includes a tubular member with an internal sidewall, and a composite wick structure including a multi-layer woven mesh and a sintered-powder layer. The multi-layer woven mesh is curled to cover on and extend over the internal sidewall. The sintered-powder layer is coated on a portion of the multi-layer woven mesh and the internal sidewall to extend along a longitudinal direction of the tubular member. By the strong capillary force provided by the sintered-powder layer, the working fluid at the liquid phase easily reflows back to the bottom of the heat pipe, such that the heat transmission efficiency is greatly enhanced.
