PROBLEM TO BE SOLVED: To provide a cylinder head capable of suppressing distortion of the whole cylinder head and greatly reducing time and cost of spending on removal processing of the distortion.SOLUTION: A cylinder head 1 includes a plurality of combustion chamber surfaces 10, 20, 30, and 40 facing a combustion chamber of an internal combustion engine. In the cylinder head, a valve seat is provided in which a clad layer is formed by means of laser cladding work on a port opening towards the combustion chamber surfaces 10, 20, 30, and 40. Slits 15, 25, and 35 are formed between the combustion chamber surfaces 10, 20, 30, and 40 adjacent to the cylinder head 1. |
