1 . A laminate comprising: 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≤ S a /S all ≤0.55 (i) 0.010 mm 2 ≤S ave ≤10.0 mm 2 (ii) 1<( h+t )/ t≤ 10 (iii) wherein, in the (i), S a represents a total area of the protrusion(s) in an observed image obtained by observing the opposed surface under an optical microscope, S all represents an area of the opposed surface in the observed image, in the (ii), S ave represents an average area of the protrusion(s) in the observed image, and in the (iii), h represents a height of the protrusion(s), and t represents a thickness of the electrode for electrolysis. 2 . The laminate according to claim 1 , wherein the protrusions are each independently disposed in one direction D 1 in the opposed surface. 3 . The laminate according to claim 1 , wherein the protrusions are sequentially disposed in one direction D 2 in the opposed surface. 4 . The laminate according to claim 1 , wherein a mass per unit area of the electrode for electrolysis is 500 mg/cm 2 or less. 5 . The laminate according to claim 1 , wherein the electrode for electrolysis is an electrode for a cathode.
