Provided is an internal combustion engine that can reduce the intensity of vibration acting on an electromagnetic wave element provided to a head part of an ignition coil. An internal combustion engine (20) comprises an internal combustion engine main body (28) and a substantially columnar ignition coil (30). A head part (32) at one end of the ignition coil (30) is provided with an electromagnetic wave element (35) for outputting electromagnetic waves irradiated into a combustion chamber (24) of the internal combustion engine main body (28), and a plurality of support members (41, 42) are provided for supporting the ignition coil (30) when an attachment part (33) at the other end of the ignition coil (30) is attached to a spark plug (26), the support members (41, 42) supporting the ignition coil (30) either at or near a nodal point (50) in a characteristic vibration mode of vibration occurring in the ignition coil (30) along with vibration of the internal combustion engine main body (28). The ignition coil (30) is not supported on the side toward the head part (32) relative to the support member (41) nearest the head part (32). |
