Provided are an electrode for electrolysis having excellent durability against reverse current, and a method that enables production of the electrode for electrolysis at low cost. The electrode for electrolysis 130 includes a conductive substrate 132 on which a catalyst layer is formed, and a reverse current absorption body 134 that is coupled to the conductive substrate 132 in a detachable manner, wherein the reverse current absorption body 134 is formed from a sintered compact containing nickel. The method for producing the electrode for electrolysis 130 includes a sintered compact formation step of obtaining the sintered compact by sintering a raw material powder composed of any one of Raney nickel alloy particles containing nickel and an alkali-soluble metal element, metallic nickel particles, and a mixture of Raney nickel alloy particles and metallic nickel particles, and a coupling step of coupling the sintered compact to the conductive substrate 132.
