The invention relates to a micro-fluidic chip and a micro-fluidic chip system for single cell analysis and a single cell analyzing method. The micro-fluidic chip for single cell analysis comprises a transparent top cover, a microfluid channel, a substrate with a micropore array and a bottom plate with a cavity body, which are sequentially connected from top to bottom in a sealing manner, wherein the transparent top cover is provided with an inflow hole and an outflow hole which are used for communicating the outside and the microfluid channel, the micropore array of the substrate is arranged below the microfluid channel and is communicated with the microfluid channel, each micropore is internally provided with an electrode, each electrode is provided with a cathode and an anode, each micropore can contain a single cell only, the bottom of each micropore is provided with a channel which is communicated with the cavity body of the bottom plate, and the cross section of the channel is smaller than the size of each single cell. With the adoption of the micro-fluidic chip, the micro-fluidic chip system and the single cell analyzing method, the capturing, identifying and disruption processes of each single cell are integrated on one micro-fluidic chip; as a corresponding operation method is provided, the content of each single cell is rapidly acquired and accurately analyzed.
