ABSTRACT:
A slat for blinds such as Venetian blinds made up of a core plate made of metal, FRP or wood and a pair of surface layers laminated on both faces of the core plate via intermediates. The laminated construction well suppresses generation of harsh noises otherwise caused by slat colliding and dewing even when used in wet environments.
