たことを特徴とする自動車用インシュレータ。The above-mentioned sound insulation insulator comprises a sound insulation mat made of a heavy sheet formed to match the floor shape of a partition wall separating an engine room and a passenger compartment, and a sound absorption layer bonded to the back side of the sound insulation mat. The mat is divided into a through-hole formed area and a non-through-hole formed area surrounding this area, and on the back side of the through-hole formed area, a sound absorbing material made of urethane foam is provided with through holes formed at the same positions. An insulator for an automobile, characterized in that the layers are integrated, and a felt sound absorbing layer is pasted and attached to surround the sound absorbing layer in the area where no through holes are formed.
