BUILDING BOARD

To prevent an appearance of a wall surface constituted of a building board where pseudo joints are formed to a design surface from being spoiled.SOLUTION: A design pattern part of a building board 10 has: multiple pattern units located side by side to a first direction; and pseudo joints extending up to both ends of the design pattern part in a second direction and partitioning the pattern units located side by side in the first direction. On a design surface 14 of the building board 10, multiple band-like patterns 51 extending in the second direction and having widths in the first direction wider than joint widths of the pseudo joints and multiple fine line patterns 53 extending in the second direction and having widths in the first direction narrower than the joint widths of the pseudo joints 31 are formed by coating per pattern unit.SELECTED DRAWING: Figure 6 【課題】意匠面に疑似目地が形成された建築板において、この建築板により構成された壁面の美観を損ねないようにすることを目的とする。【解決手段】建築板１０の意匠柄部は、第１方向に隣り合って位置する複数の柄ユニットと、第２方向において意匠柄部の両端まで延び、第１方向に隣り合って位置する柄ユニットを区画する疑似目地を有している。建築板１０の意匠面１４には、柄ユニット毎に、第２方向に延び、第１方向での幅が疑似目地の目地幅よりも広い複数の帯状模様５１と、第２方向に延び、第１方向での幅が疑似目地３１の目地幅よりも狭い複数の細線模様５３と、が塗装により形成されている。【選択図】図６
