PROBLEM TO BE SOLVED: To provide an electrode for an undersea characteristics measuring instrument capable of stably measuring an electric field and an electric potential by eliminating the effect of noise caused by liquid-flow generated inside a case, and reducing a time required until a measurement. SOLUTION: An electrode 1 includes a case 10 having an opening for introducing an outside electrolyte 30 inside; an electric potential detecting element 11 consisting of Ag/AgCl, for instance, arranged in the case 10; a filter 12 mounted to the opening of the case 10; and a nonwoven cloth 15 filled in the case 10 as a liquid-flow-prevention material. If the electrode 1 is immersed into the electrolyte 30 when an electrolyte is not penetrated into the nonwoven cloth 15, the electrolyte 30 is quickly penetrated into the nonwoven cloth 15 through the filter 12 of the case 10 without causing water flow in the case 10, and the electrolyte 30 and the electric potential detecting element 11 are electrically connected well in a short period of time.
