The present invention relates to a y-type inclined lithium target for generating high power neutrons, comprising a pair of target modules comprising a substrate extending to a predetermined width and a solid target provided on one surface of the substrate, wherein the pair of target modules are installed at a first angle with respect to each other and are disposed at a second angle with respect to a direction in which a particle beam is irradiated. The y-type inclined lithium target for generating high power neutrons according to the present invention has the advantage of being capable of maximizing a heat transfer area. In addition, since the target is configured as a pair of target modules, each of the target modules can be miniaturized. Accordingly, generation and accuracy of a lithium layer can be improved, and the advantage of easy storage is provided.
