<p>It is an object of the present invention to provide a panel capable of obtaining sufficient strength, weight reduction and sound absorbing performance. Referring to panels 17 and 18, a space 22 is formed by an inner thin plate 23 fixed to the inner surface of an outer thin plate 21, and a foam material 24 is filled in the space 22. The foam material 24 is preferably a highly foamable rubber sound absorbing material. In the inner thin plate 23, a perimetrical side part 25 and perimetrical edge part 26 for forming the space 22, and a concave part 27 for enhancing the strength of the panel are drawn to the side of the outer thin plate 21. The bottom faces of the perimetrical edge part 26 and concave part 27 of the inner thin plate 23 are bonded to the outer thin plate 21 using a thermosetting adhesive.</p> |
