PROBLEM TO BE SOLVED: To provide a foamed decorative material which has excellent compression recoverability even when foamed with a high magnification, is recoverable from crushing due to self weight of the product during storage and/or yielding by the pressing roller during processing or collapse by laying marks after processing and is not impaired in design by embossing. SOLUTION: The heat-expansible microcapsule foaming agent for the foamed decorative material consists of at least a heat-expansible microcapsule foaming agent (a) and a heat-expansible microcapsule foaming agent (b). The foaming agent (a) has an average particle size of raw particles of 5-35μm, an amount of an inclusion gas of 10-35% and a film thickness of the shell on maximum foaming of 0.03-0.10μm, and the foaming agent (b) has an average particle size of raw particles of 5-35μm, an amount of the inclusion gas of 10-35% and a film thickness of the shell on maximum foaming of 0.10-0.25μm.
