Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a foam which can be used in an absorbent article, etc., and to provide a method for generating the same.SOLUTION: The method for generating the foam includes: adding at least one froth stabilizing surfactant to an aqueous dispersion, comprising a thermoplastic resin, water, and a dispersion stabilizing agent, to form a mixture; adding a fiber to the mixture; and frothing the mixture to create a froth; removing at least a portion of the water in the froth to create a foam, wherein the foam generated has a non-cellular fibrillated morphology. The foam having the fibrillated non-cellular structure has an average density of about 0.02 g/cmto about 0.07 g/cm.
