PROBLEM TO BE SOLVED: To provide a wood brick which improves an accuracy of a spraying work of rigid urethane foam and is efficiently constructed, so as to shorten a work period and to reduce cost of labor. SOLUTION: The wood brick, forming ramps on the surface along both long-side direction and short sides, to which a release agent or a mold-releasing agent is applied for an easier removal after the spraying work, or otherwise a seal for the same purpose is attached while an adhesive is set in a bottom thereof.
