Abstract
A foam molding method includes: sealing a core material and a skin material with a sealing part; and molding a foam layer on the inside of the sealing part. The sealing of the core material and the skin material with the sealing part includes sealing the core material and the skin material so that the sealing part includes a self sealing part for which an edge part of the skin material is housed in a recess provided in the core material, a clamp sealing part sealed by clamping the core material and the edge part of the skin material by foam molding molds, and a crimp sealing part arranged in a switchover part between the clamp sealing part and the self sealing part, and sealed by crimping the edge part of the skin material to the core material.
