In a cylinder head 1 of an internal combustion engine, communicating passageways 17, 18, 17', 18' for coolant are provided between combustion chambers 3 and pass-through holes 21 to 28 at positions which overlap straight lines L1, L2 connecting centers C2, C3 of the exhaust port openings 6a, 7a with centers C5 to C8 of the pass-through holes 25 to 28 and straight lines L3, L4 connecting centers C9, C10 of the intake port openings 4a, 5a with centers C11 to c14 of the pass-through holes 21 to 24 when a mating surface 2 of the cylinder head 1 with the cylinder block is viewed from the bottom. When peripheries of the exhaust port openings 6a, 7a and intake port openings 4a, 5a thermally expand, the suppression of thermal expansion by the bolts at fastening portions is alleviated by the communicating passageways 17, 18, 17', 18'.
