The invention discloses a solid non-polarized electrode and a manufacturing method thereof. The solid non-polarized electrode comprises a PVC (Polyvinyl Chloride) pipe, a copper wire and a spiral leadwire, wherein the spiral lead wire is fixed in the PVC pipe by virtue of a plastic filling agent; a PVC top cover is arranged at the upper end of the PVC pipe; a straight end of the spiral lead wirepenetrates out of the PVC top cover and is connected with one end of the copper wire; and the other end of the copper wire is connected with a sheath clamp. According to the method, materials are easily purchasable, the method is simple and easy to learn, and the operability is high. The solid non-polarized electrode manufactured according to the method has the advantages of being wide in appliedenvironment, low in cost, reliable in performance, portable, durable in use, easy to preserve, convenient to use and transport and the like.
