Summary:To provide a woody fire-resistant member which is arranged on a main structural part which bears an external load, is provided with a texture of wood on an outer cover part, and suppresses permeation of moisture into the wood.SOLUTION: A woody fire-resistant member 1 comprises a load supporting part 2, a fire-resistant covering layer 3 coated around the load supporting part 2, and a finishing wood layer 4 provided on the outside of the fire-resistant covering layer 3. The fire-resistant covering layer 3 is made of a wet fire-resistant covering material, and a moisture barrier layer 5 is formed between the load supporting part 2 and the fire-resistant covering layer 3 and between the fire-resistant covering layer 3 and the finishing wood layer 4.SELECTED DRAWING: Figure 1 【課題】外荷重を負担する主要構造部分に配置される木質耐火部材であって、木材の持つ質感を外被部に備え、かつ、木材への水分の浸透を抑制した木質耐火部材を提供する。【解決手段】荷重支持部２と、荷重支持部２の周囲に被覆された耐火被覆層３と、耐火被覆層３の外側に周設された仕上げ木材層４とを備える木質耐火部材１であって、耐火被覆層３が湿式耐火被覆材からなり、荷重支持部２と耐火被覆層３との間、および、耐火被覆層３と仕上げ木材層４との間に、水分遮断層５が形成されている。【選択図】図１
