A panel for an elevator composed of a surface plate and a corrugated reinforcing member having ridges facing the surface plate with the surface plate and the corrugated reinforcing member being joined to each other by a room temperature curing modified acrylate adhesive of a two-part non-solvent type applied in flat layers in an unmixed condition to the entire crest of the ridges and surface portions of the surface plate facing the ridges. The elevator panel thus formed retains the adhesive in a satisfactorily cured condition with a high level of adhesive strength while providing a greatly improved level of soundproofing and damping as well as ease of fabrication.
