Abstract

A method of manufacturing a multiple uneven plate having multiple uneven portions, the multiple uneven portions having large protruding degree of each of the concave or convex portions, the concave or convex portions adjacent to one another includes the steps of forming a plurality of grooves, so that in the grooves the plate thickness is reduced and bending the plate to form a plurality of crest and trough lines crossing the grooves.
