▎ 摘　　要

NOVELTY - A graphene sheet is grown on a graphene growth support comprising a carbonization catalyst, and comprises one or more ripples. The ripple is formed using at least difference between thermal expansion coefficient of the graphene growth support and thermal expansion coefficient of the graphene sheet. USE - Graphene sheet used as electrode material used in devices (claimed) e.g. electric and electromagnetic devices e.g. next-generation field effect transistor, diode, high-end sensor e.g. pixels of display, bio tape, surgery gloves, surface sensor of multi-joint robot and hemispherical optoelectronic device. ADVANTAGE - The graphene sheet has excellent deformation capability and exhibits suppressed change in mechanical properties and electrical properties. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) graphene sheet unit, which has the graphene sheet having a profile which repeatedly rises and falls, and an elastic material (40) contacting the graphene sheet; (2) device having the graphene sheet; and (3) graphene sheet support unit, which has the graphene sheet and graphene growth support. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the graphene sheet having profiles which repeatedly rise and fall. Elastic material (40) Wavy shape (W)
