▎ 摘　　要

NOVELTY - The composition comprises 100 pts. wt. copper, 25 pts. wt. graphene and an organic binder. The copper has a spherical powder form. The graphene is coated on the surface of the copper powder and includes silver. USE - Copper-graphene paste composition for forming electrode of piezoelectric element. ADVANTAGE - Oxidation of copper can be prevented when used as an electrode of a piezoelectric element. Manufacture of piezoelectric element with a low specific resistance and a high piezoelectric coefficient is possible.
