To provide inexpensive fireproof lumber which exhibits an excellent carbon dioxide discharge reduction effect.SOLUTION: The fireproof lumber has a body part formed by lumber, and a fireproof part. The fireproof part has at least a one-stage fireproof layer. The fireproof layer of each stage has a fire-retardant adhesive layer formed by a fire-retardant adhesive containing a fire retardant and a burning margin layer formed by lumber in this order from the body part toward the fireproof part.SELECTED DRAWING: Figure 2
【課題】二酸化炭素の排出削減効果に優れ、安価な耐火木材を提供する。【解決手段】木材によって形成される本体部と、耐火部とを有し、前記耐火部は少なくとも１段の耐火層を有し、各段の耐火層は、前記本体部から前記耐火部に向かう方向に、難燃剤を含有する難燃性接着剤によって形成される難燃性接着剤層と、木材によって形成される燃え代層とをこの順に有する、耐火木材。【選択図】図２
