The invention provides an electrode connecting plate which comprises a bottom plate (3), a guide rod (5) and a guide plate (6), wherein the bottom plate (3), the guide rod (5) and the guide plate (6) are made of a solid conductive material; the bottom plate (3) is in electric connection with the guide plate (6) through the guide rod (5); the electrode connecting plate further comprises a pressing plate (2); the pressing plate (2) can clamp the electrode, so as to enable the electrode to be fixed between the pressing plate (2) and the bottom plate (3); one end of the electrode connecting plate is connected with a pole tower or the ground terminal of a grounding apparatus, and the other end of the electrode connecting plate is connected with a graphite grounding electrode; the electrode connecting plate is partially or totally buried in the ground. The electrode connecting plate has the benefits that in order to meet different requirements of burying depths, the electrode connecting plate is connected with components which are arranged at the two ends of the connecting plate in a welding manner, the electrode connecting plate further adopts a metal material with better conductivity, the rigidity, strength and electrical conductivity of the overall connecting plate can be further ensured.
