The invention belongs to the technical field of lithium or lithium alloy detection, and provides a lithium strip or lithium alloy strip microscopic sample as well as a preparation method and a metallographic structure characterization method thereof. The preparation method of the lithium strip or lithium alloy strip microscopic sample comprises the following steps: pressing a lithium ingot or a lithium alloy ingot in a protective atmosphere to obtain a strip; and cutting the strip to obtain the lithium strip or lithium alloy strip microscopic sample. The sample preparation efficiency is high, the obtained microscopic sample is smooth in surface, free of foreign matter and deformation and free of an interference layer, and the accuracy of a detection result can be guaranteed. The invention also provides a metallographic structure characterization method of the lithium strip or lithium alloy strip microscopic sample, which comprises the following steps: corroding the lithium strip or lithium alloy strip microsc
