The utility model discloses a micro-fluidic chip with a three-dimensional electrode. The micro-fluidic chip comprises a sealing sheet and a structural sheet, the structural sheet comprises a substrate layer, a channel layer and an electrode guide layer. The channel layer and the electrode guide layer are respectively positioned on the upper and lower surfaces of the substrate layer; and the three-dimensional electrode is positioned in the center of the microchannel in the channel layer and is connected with the corresponding electrode lead on the electrode guide layer on the other side by penetrating through the electrode guide hole of the base material layer. According to the micro-fluidic chip disclosed by the utility model, uniform electric field distribution in the longitudinal direction is ensured, and fluid can be sensed and controlled more sensitively and effectively; meanwhile, the three-dimensional electrode and the chip can be synchronously manufactured by adopting a mature integrated circuit proces
