    Abstract: A spark plug has a housing of a cylindrical shape and an insulator supported to an inside of the housing. A channel part is formed at a distal end side of the housing. The channel part is open so that the inside of the housing communicates with an outside of the housing through the channel part. The channel part has a channel bottom having a tapered shape oblique relative to a plug central axis. An overall channel bottom is arranged in the housing closer to a proximal end side than to the distal end side of the housing.
