Abstract
A panel used as a material for forming a wall of a general building material such as an elevator is constituted from a rigid front plate and a rigid back plate having a corrugated cross-section adhered to the rear side of the front plate by means of a reinforcing bonding agent made of a synthetic resin material. The synthetic resin bonding agent contains at least one hollow body in order to minimize the specific gravity of the bonding agent to reduce the weight of the panel.
