The sound absorbing-insulating structure for vehicles, in which a content rate of the synthetic resin is in the range of 0.01 to 80 wt %, and a surface density is in the range of 0.2 to 3 kg/m, is provided. This sound absorbing-insulating structure has the good sound absorbing-insulating characteristic and is light in weight and inexpensive in cost.",
