Zusammenfassung:	Provided are a constrained-type vibration-damping metal sheet having foam pores and a method for manufacturing same. The constrained-type vibration-damping metal sheet of the present invention comprises: a lower metal sheet; a foam resin film bonded to the lower metal sheet; and an upper metal sheet bonded to the foam resin film, wherein the foam resin film has foam pores comprising, by wt% of itself, 85-95% of a thermoplastic polyethylene resin having a number average molecular weight of 8000-12000, 0.1-1% of stearic acid, 1-5% of a styrene-ethylene-butadiene-styrene (SEBS) resin, 0.5-5% of a foaming agent, 1-4% of a dicumyl peroxide crosslinking agent, and 0.5-2% of ZnO foaming aid.
