DECORATIVE BOARD

To provide a decorative board that can conceal waviness, unevenness, or uneven coating of the board material due to the impressive design of the complex shadows despite the simple pattern, and that has excellent workability.SOLUTION: There is provided a decorative board that has a decorative portion (18) in which a plurality of ridge-shaped convex portions (14) and groove-shaped concave portions (16) parallel to each other are provided on the surface of a plate material (12) formed with a length-to-horizontal length ratio of 1: n (note that, n is an integer of 2 or more) in various different thicknesses. On the surface of the plate material (12), a boundary portion (20) composed of concave or convex stripes is provided at a position equally divided by the vertical length in the horizontal direction, and also the axes of the ridge-shaped convex portion (14) and the groove-shaped concave portion (16) adjacent to each other with the boundary portion (20) as a boundary are provided so as to intersect at an angle of 45° or more and 135° or less.SELECTED DRAWING: Figure 1 【課題】簡単な模様であるにもかかわらず、複雑な陰影が織りなす印象的な意匠性によって板材のうねりや段違い或いは塗装ムラなどを隠蔽することができると共に、施工性に優れた化粧板を提供する。【解決手段】縦横の長さの比が１：ｎ(但し、ｎは２以上の整数)で形成された板材(１２)の表面に、互いに平行する畝状凸部(１４)および溝状凹部(１６)が種々の異なる太さにて複数設けられた化粧部(１８)を有する化粧板であって、上記の板材(１２)の表面には、横方向に於いて縦の長さで等分する位置に凹条または凸条からなる境界部(２０)が設けられると共に、その境界部(２０)を境にして隣接する上記の畝状凸部(１４)および溝状凹部(１６)の軸線同士が、４５°以上で且つ１３５°以下の角度で交わるように設けられることを特徴とする。【選択図】図１
