Zusammenfassung:Provided are a heat-insulating and sound-absorbing material improved in construction workability, and a partition wall in which degradation in sound insulation performance is suppressed. The heat-insulating and sound-absorbing material 1 is comprised of an agglomerate of inorganic fibers, wherein the agglomerate has a density of 10 to 20 kg/m3 and the inorganic fibers of the agglomerate have a length-weighted average fiber diameter of 2.0 to 8.7 ?m, and wherein the agglomerate contains: 20 to 66% of inorganic fibers having a length-weighted average fiber diameter of less than 4.0 µm; and 13 to 58% of inorganic fibers having a length-weighted average fiber diameter of 7.0 µm or more. The partition wall comprises a hollow wall portion, and the above heat-insulating and sound-absorbing material installed in the hollow wall portion.
