PROBLEM TO BE SOLVED: To provide a plasma device using a cylinder head capable of easily providing a mechanism for combustion promotion, minimizing design man-hour of an internal combustion engine and sharing a significant number of parts with an existing internal combustion engine. SOLUTION: The plasma device using the cylinder head comprises a discharge device 810 mounted in the cylinder head 300 and having electrodes 812, 813 exposed to a combustion chamber 400, an antenna 820 disposed to protrude from the cylinder head into the combustion chamber, a bulging portion 371 made of an insulator or dielectric and formed to bulge from the cylinder head to the combustion chamber side so as to cover the antenna, an electromagnetic wave transmission passage 830 disposed in the cylinder head and having its one end connected with the antenna and its other end covered with an insulator or dielectric and extending therethrough to a cylinder head outer wall, and an electromagnetic wave generating device 840 for feeding an electromagnetic wave to the electromagnetic wave transmission passage. At a compression stroke, an electric discharge is caused by the electrode of the discharge device so that the electromagnetic wave fed from the electromagnetic wave generating device via the electromagnetic wave transmission passage is radiated from the antenna.
