Functional laminate and production method therefor

A functional laminate including a porous intermediate layer having air permeability laminated between a porous surface layer and a resin foamed layer,

• each of the porous intermediate layer and the porous surface layer having an affinity to a foaming resin forming the resin foamed layer, wherein
• the affinity of the porous intermediate layer is higher than the affinity of the porous surface layer, and
• the contact angle θm(°) of the porous intermediate layer relative to the foaming resin and the contact angle θs(°) of the porous surface layer relative to the foaming resin satisfy a relational expression below:
• 1°≤θs−θm≤30°,
• the porous surface layer includes, at a position facing the porous intermediate layer, a mixed layer part of the resin foamed layer and the porous surface layer, and
• the thickness of the mixed layer part is 0.05 to 3 mm.
