Abstract

A method for synthesizing diamond wherein hydrogen gas which has passed through a micro-wave non-electrode discharge and mixed with hydrocarbon gas, or a mixture gas consisting of hydrocarbon and hydrogen after its passing through a micro-wave non-electrode discharge, is introduced onto the surface of a substrate heated to a temperature of from 300.degree. to 1300.degree. C. to decompose hydrocarbon in its energetically activated state for the diamond deposition.
