Provided is a loop type micro heat transport device including: a lower plate having a reservoir for storing operating fluid at its upper surface, an evaporating part spaced apart from the reservoir to evaporate the operating fluid, and a condensing part for condensing vapor evaporated from the evaporating part; and an upper plate engaged with an upper surface of the lower plate and formed at a position corresponding to the evaporating part and the condensing part, and including a vapor space having a vapor line through which the vapor evaporated from the evaporating part is transported to the condensing part, wherein the operating fluid is circulated through the reservoir, the evaporating part, and the condensing part. Therefore, it is possible to remarkably improve productivity since its simple structure helps to make the manufacture simple, as well as to improve cooling performance and enabling long distance heat transport.
