PROBLEM TO BE SOLVED: To provide a confirmation system for connection state of grounding system, can greatly reduce labor related to the confirmation work of the state of a grounding system after grounding work, and rapidly confirm and grasp whether a grounding system operates normally at a lapse of time even at a location other than the one where grounding work has been executed. SOLUTION: In a protection ground conductor 107 where the neutral line side of the secondary winding of a transformer 100 interposed in an electric circuit is grounded, and a second electrical terminal 105 provided on the earth grounds equipment, or the like via a grounding conductor 106 at the load side of the transformer 100, and in the electric circuit having an electrically connected grounding system, the confirmation system for connection state of grounding system is provided with a grounding system state data generation unit 300 for generating grounding system state data and transmitting the data from a transmission section, and an intensive unit 400 that receives the grounding system state data and has a storage section for holding the grounding system state data, thus holding the intensive data of the grounding system state data in the intensive unit 400.
