Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cooling structure for a cylinder block, in which uniform cooling can be realized. SOLUTION: This cooling structure 1 for a cylinder block is provided with a cylinder block 10 in which a water jacket 12 is continuously provided around a bore wall 11b enclosing a plurality of bore ranges 111, 112, and 113, and a water jacket spacer 20 inserted into the water jacket part 12 to form a gap to the bore wall 11b. Cooling medium is supplied to the water jacket part 12, so that temperature of the bore wall 11b is equalized. In the cylinder block 10, inter-bore ranges 10b positioned around the boundaries between adjoining two of the bore ranges 111, 112, and 113, and the other ranges 10a are provided. Area of the gap between the bore wall 11 and the water jacket spacer 20 in the inter-bore range 10b is smaller than area of the gap between the bore wall 11b and the water jacket spacer 20 in the other range 10a.
