Summary:PROBLEM TO BE SOLVED: To provide a system ceiling in which ceiling boards 10 and ceiling facility equipment are placed on a ceiling substrate formed by assembling, in a lattice form, bar members 6 suspended from a ceiling slab 1 to support them, the system ceiling that makes the sagging (deformation) in the center of the ceiling board 10 inconspicuous.SOLUTION: Granular painting including particles 13 having an average particle diameter of a coating film thickness (t) of a decorative coating film 12 or more and 1 mm or less, is applied to an indoor side surface of the ceiling board 10. Even if a central part M of the ceiling board 10 sags, a shadow is made by light incident on granular parts 14 composed of the particles 13 projected from the coating film 12 in its peripheral edge part C to generate a shadow over the whole ceiling board 10, so that the whole ceiling board 10 is made apparently uniformly visible to make the sagging (deformation) of the central part of the ceiling board 10 inconspicuous. 【課題】天井スラブ１から吊り下げられたバー材６を格子状に組んだ天井下地に対し天井板１０を天井設備機器と共に載せ掛けて支持したシステム天井において、天井板１０中央部の垂れ下がり（撓み）を目立ち難くする。【解決手段】天井板１０の室内側の表面に、平均粒径が化粧塗膜１２の塗膜厚さｔ以上でかつ１ｍｍ以下の粒子１３，１３， を含む粒状塗装を施す。天井板１０の中央部Ｍが垂れ下がっても、その周縁部Ｃでは、塗膜１２から突出した粒子１３，１３， からなる粒状部分１４，１４， に当たる光により影を作って、天井板１０全体に影を発生させ、見掛け上、天井板１０全体が均等に見えるようにして、天井板１０中央部の垂れ下がり（撓み）を目立ち難くする。【選択図】図６
