[Problem to be Solved] In a laminated material based on a honeycomb material, there has been such a problem that the bonding between a honeycomb material serving as a base and two face materials between which the honeycomb material is sandwiched requires bonding between planar members having great rigidity with a high degree of planar accuracy and honeycomb members that are linear and not completely flat, thus making it to obtain a great deal of bonding force. [Solution] A honeycomb panel laminate includes a sound absorbing face, a sound absorbing layer, and a sound insulating face. The sound absorbing face is made of a foam. The sound absorbing layer is composed of a honeycomb material and a layer obtained by filling spaces with a hard foam material. The honeycomb panel laminate has a structure obtained by bonding the honeycomb material to the sound absorbing face by applying an adhesive to edges of the honeycomb material of the sound absorbing layer and pressing the edges against the sound absorbing face so that the edges bite into the foam. The sound insulating face, which faces the sound absorbing face across the honeycomb material, is made of a foam, and has a bonded structure obtained by applying an adhesive all over a surface of the sound insulating face that makes contact with the honeycomb material and pressing opposite edges of cell walls of the honeycomb material against the sound insulating face so that the opposite edges bite into the surface, all over which the adhesive has been applied, of the foam. |
