Abstract
The present invention provides a foamed member capable of inhibiting or preventing foam breakage at the time when the foam member is peeled from a carrier tape, even when the foamed member has a high expansion ratio. The foamed member has a thermoplastic resin foam layer containing a thermoplastic resin foam formed through a step of impregnating a high-pressure inert gas into a thermoplastic resin and subsequently reducing pressure, and at least one of a thermoplastic polyester-based resin layer and a thermoplastic elastomer resin layer disposed on at least one side of the thermoplastic resin foam layer.
