PROBLEM TO BE SOLVED: To eliminate the need for the conventional seal member to reduce the number of parts and assembly man-hours, by providing structure in which a flange mounting bolt does not passes through a blowby gas passage, to uniform fastening surface pressure of the flange mounting bolt, by uniforming mounting(fastening) pitches of mounting flanges of an intake manifold, and to make a whole engine compact, by shortening the whole length of the mounting flange, in a cylinder head of a multi-cylinder engine. SOLUTION: Cylinders of the multi-cylinder engine are arranged at equal intervals in a cylinder row direction. A head mounting boss part having a head mounting hole through which a head mounting bolt is inserted is disposed at the center between the cylinders. The flange mounting boss part is offset and disposed inside the head mounting boss part. Offset amounts of the head mounting boss part and the flange mounting boss are increased, as they are separated from the center between the cylinders in the cylinder row direction.
