This invention provides a cylinder head capable of efficiently cooling the portion at which a large number of valve ports gather. The present invention provides a cylinder head (20) of an engine equipped with suction and exhaust valve ports (3a, 5a) inside a cooling jacket (8), characterized in that a drain port (11) allowing the cooling water jacket (8) to communicate with the outside of the cylinder head (20) opens in a corner portion at one end portion of a side wall (1a) of the cylinder head, water feed ports (10a) extending along the side wall (1a), opening to the cooling water jacket (8) and communicating with the cooling water jacket of the cylinder block are formed in a cylinder bottom wall (1c), and a partition is so disposed as to divide the portion at which the water feed ports (10a) are open and the portion at which the suction and exhaust valve ports (3a, 5a) are disposed and to guide cooling water from the water feed ports (10a) round the suction and exhaust valve ports (3a, 5a).
