<P>PROBLEM TO BE SOLVED: To provide a wall material which hardly deteriorates designability because breakage of its surface is inhibited even when the plurality of wall materials are loaded in such a manner that unevenly-formed surfaces formed on the surfaces face each other, in the case of the loading of the plurality of wall materials. <P>SOLUTION: In a wall material, a plurality of depressions 2, 2... are formed on a surface of a base material 1. In the formation of the wall material, a surface height H<SB POS="POST">A</SB>of a high-density area A formed in such a shape that an interval T<SB POS="POST">A</SB>between the adjacent depressions 2 and 2 is short is set lower than a surface height H<SB POS="POST">B</SB>of a low-density area B formed in such a shape that an interval T<SB POS="POST">B</SB>between the adjacent depressions 2 and 2 is long. <P>COPYRIGHT: (C)2013,JPO&INPIT |
