Electrode for electrolysis and laminate

Abstract

A laminate containing: an electrode for electrolysis; and a membrane, wherein the electrode for electrolysis has one or a plurality of protrusions on a surface opposed to the membrane, and the protrusion(s) satisfies/satisfy the following conditions (i) to (iii): 0.04≤Sa/Sall≤0.55  (i) 0.010 mm2≤Save≤10.0 mm2  (ii) 1<(h+t)/t≤10  (iii) wherein, in the (i), Sa represents the total area of the protrusion(s) in an observed image obtained by observing the opposed surface under an optical microscope, Sall represents the area of the opposed surface in the observed image, in the (ii), Save represents the average area of the protrusion(s) in the observed image, and in the (iii), h represents the height of the protrusion(s), and t represents the thickness of the electrode for electrolysis.
