A laminated pillar (1) is composed of five lumber-boards (4) laminated and bonded together in the thickness direction. Each lumber-board 4 has a first board portion (5) that is the portion positioned at the ground end, formed of a first type of wood such as Japanese cedar or the like that has excellent resistance to corrosion, dirt, and ants, and a second board portion (6) formed of a second type of wood that is cheap, such as whitewood or the like. These board portions (5), (6) are bonded together in the axial direction by means of finger joints (7). In the laminated pillar (1) comprised by a bonded lamination of the lumber-boards 4 thus configured, the portion at the ground end is first laminated lumber portion (2) formed of the first type of wood, and therefore does not require corrosion-proofing/ant-proofing treatment. Therefore, structural laminated lumber can be realized that is low-priced and facilitates on-site work.
