PROBLEM TO BE SOLVED: To provide a method for producing a foamed sheet capable of obtaining a foamed sheet which is hardly broken and has high flexibility in spite of having a thin thickness by being compressed.SOLUTION: A method for producing a foamed sheet includes: a foaming step of foaming a resin composition, and obtaining a foamed body in which a plurality of air bubbles are exposed to the surface of the outside of a first surface portion in one side in a thickness direction, and a second surface portion in the other side in the thickness direction is a skin layer; and a heating and compressing step of heating and compressing the foamed body, and obtaining a foamed sheet in which a plurality of air bubbles are exposed to the surface of the outside of the first surface portion in one side in the thickness direction and the second surface portion in the other side in the thickness direction is the skin layer. The heating and compressing step heats and compresses the foamed body from the side of the second surface portion.SELECTED DRAWING: Figure 1 |
