PROBLEM TO BE SOLVED: To provide a cylinder block structure made of light alloy die cast of good quality to wrap parts for various engines with high precision when parts for various engines are cast in a cylinder block by die cast, in a cylinder block structure die-cast-molded by using a light alloy material. SOLUTION: A cylinder liner 2 integrally having an upper wall 2a forming the ceiling wall of an engine combustion chamber is molded by, for example, an aluminum light alloy material being the same main component as that of a cylinder block 1 and cast in the cylinder block 1. Preferably, by fixing a cooling water chamber forming plate 20, molded by a light alloy material having the same main component as that of the cylinder block 1, on the outer periphery of the cylinder liner 2, the cylinder liner 2 provided on its outer periphery with a cooling water chamber 21 is cast in the cylinder block.
