Method of producing laminated plate

Abstract

A method of producing a laminated plate comprises the steps of (a) preparing a pair of blocks in each of which a plurality of plate elements overlap each other in an inclined position such that the plate elements have one end portions appearing stepwise at predetermined intervals on one surface of the block and the other end portions appearing flat on the other surface of the block, and (b) interlocking and bonding the two blocks to each other such that the one end portions of the plate elements in one of the blocks and the one end portions of the plate elements in the other block oppose each other in a predetermined positional relationship, whereby a laminated plate opposite major surfaces of which are flat is produced.
