Abstract
In a dashboard insulator for a vehicle, an inner layer laminated between front and rear layers is formed by laminating fusion, barrier and other fusion films and has a large number of small holes with a uniform opening rate. The both layers are formed by a thermoplastic material with predetermined basis weight, and Young's modulus. The both fusion films formed by a thermoplastic material with a melting point lower than that of the barrier film fuse the both layers to the barrier film. Each fusion part of the both fusion films has a predetermined fusion force in its predetermined range.
