PROBLEM TO BE SOLVED: To provide a bilayer foam molding method capable of infiltrating a second layer part into a gap part mainly between a common mold pressing contact part of a first layer part and a common mold. SOLUTION: In the bilayer foam molding method, the molding of a bilayer foam molded article 31 in which the first layer part 22 and the foaming second layer part 23 are integrated is performed according to: a first layer molding process for performing the molding of the first layer part 22 by using the common mold 24 and a mold 25 for the first layer molding; and a second layer molding process for performing the molding of the foaming second layer part 23 by using the common mold 24 while leaving the molded first layer part 22 as it is and a second layer molding mold 26. Therein, the second layer molding process is performed while forming the gap part 61 between the common mold pressing contact part of the first layer part 22 molded in the first layer molding process and the common mold 24 and, thereby, the second layer part 23 is infiltrated from a marginal part of the first layer part 22 to the gap part 61 and, thereby, an infiltrated part 60 integrated with the second layer part 23 is formed on the marginal part of the common mold pressing contact part of the first layer part 22.
