  "textContent": "Provided are a lithium ion secondary battery electrode that occurrence of short-circuit and contamination can be reduced and the method for manufacturing such a lithium ion secondary battery electrode. An electrode used for a lithium ion secondary battery includes a current collector formed of a metal porous body. The current collector has a mixture layer impregnated with an electrode material mixture containing an electrode active material and a non-mixture-impregnated portion not impregnated with the electrode material mixture and including a tab portion and a tab converging portion. The surface roughness Ra of the non-mixture-impregnated portion is equal to or less than the surface roughness of the mixture layer.",
