▎ 摘　　要

NOVELTY - A graphene laminate (1) comprises a hydrogel layer (3) comprising water, a gelatinizer, and a reducing agent, provided on the side(s) of a graphene sheet (2). USE - Graphene laminate is used for manufacturing graphene sheets (all claimed) of electrode materials of electrical storage device e.g. lithium secondary battery and lithium ion capacity, and electroconductive circuits of electric products. ADVANTAGE - The graphene laminate has stable electroconductivity. The conveyance speed of graphene film is gathered when formed on a film roll. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of graphene laminate, which involves laminating hydrogel layer on graphene oxide sheet and reducing the graphene oxide sheet; and (2) manufacture of graphene sheet, which involves removing the hydrogel layer. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the graphene laminate. Graphene laminate (1) Graphene sheet (2) Graphene layer (2a) Base material (2b) Hydrogel layer (3)
