  "textContent": "Provided is a laminate for a secondary battery in which separator curling up is inhibited. A method of producing a laminate for a secondary battery includes: a step (A) of producing an affixed body including a negative electrode material and separator webs affixed to both surfaces of the negative electrode material or an affixed body including a negative electrode material, a first separator web, a positive electrode, and a second separator web affixed in stated order; and a step (B) of cutting the affixed body. The step (A) includes a step (a1) of applying an adhesive material at affixing surfaces of the negative electrode material and the separator webs. The adhesive material is applied in the step (a1) such that a first coated section including a region where the adhesive material is applied with a coating weight M1 and a second coated section including a region where the adhesive material is applied with a coating weight M2 (≥M1+0.02 g/m) are located alternately in a longitudinal direction. The affixed body is cut within a range where the second coated section is located in the step (B). The positive electrode is located at a position opposite the first coated section.",
