Abstract
A structure member includes a first plate member formed from a thin metal plate and having a plurality of frusto-pyramid projections arranged in a staggered fashion, and a second plate member formed from a thin metal plate and having a plurality of frusto-pyramid projections having dimensions different from those of the projections of the first plate member and arranged in a staggered fashion. The first and second plate members are overlapped in such a manner that tip ends of the frusto-pyramid projections of the plate members are opposed to each other but are not overlapped with each other, and overlapped and contacted portions are joined together to form a single plate body.
