PROBLEM TO BE SOLVED: To provide a device for synthesizing diamond, capable of synthesizing high quality and highly reliable diamond at a high speed by a device and method which are more inexpensive than the conventional art.SOLUTION: A device 10 for synthesizing diamond includes: a reactor 1 capable of achieving a vacuum state of 100 Pa or below; a cathode 3A and an anode 3B provided in the reactor 1; an arc source 7 for generating arc discharge between both electrodes 3A and 3B; and a substrate 2 irradiated with ionized carbon generated from the electrodes. At least one of both electrodes 3A and 3B is a carbon source. Accordingly, diamond can be synthesized on the substrate 2 easily and at a high speed without using carbon-containing gas or a carbon-containing liquid. |
