Summary: | To provide a foam-molded product in which poor appearance such as pockmarks and swirls are suppressed, a method of manufacturing a foam-molded product capable of suppressing poor appearance of the foam-molded product, and a method of suppressing poor appearance of the form-molded product.SOLUTION: There are provided: a foam-molded product including a foam layer, and a skin layer covering the foam layer, wherein a maximum diameter of bubbles in the foam layer is 0.50 mm or less, in the foam layer, an average diameter of the bubbles measured in a same cross section as a maximum diameter of the bubbles is 0.05 mm to 0.15 mm and the bubbles having the maximum diameter and the average diameter are formed by thermal decomposition of a blowing agent; a method for manufacturing a foam-molded product; and a method for suppressing an appearance defect of a foam-molded product.SELECTED DRAWING: Figure 2
