PROBLEM TO BE SOLVED: To provide a decorative laminate which has excellent hardness, is hard to be scratched and has excellent workability.SOLUTION: There is provided a decorative laminate 100 which comprises a melamine-based resin layer 11 containing a melamine-based resin which is a reaction product of a melamine compound, a guanamine compound and an aldehyde compound, where the Martens hardness of the surface of the melamine-based resin layer 11 is 300 to 700 N/mmand the ratio of the unreacted product of the guanamine compound contained in a melamine-based resin used for forming the melamine-based resin layer 11 is 0.1 to 20.0 mol%. The decorative laminate 100 further comprises a core material layer 12.SELECTED DRAWING: Figure 1 【課題】優れた硬度を有し、傷が付き難く、かつ、加工性に優れた化粧板の提供。【解決手段】メラミン化合物とグアナミン化合物とアルデヒド化合物との反応生成物であるメラミン系樹脂を含むメラミン系樹脂層１１を備え、メラミン系樹脂層１１の表面のマルテンス硬度が３００〜７００Ｎ／ｍｍ２であり、メラミン系樹脂層１１を形成するために使用するメラミン系樹脂に含まれる前記グアナミン化合物のうち未反応物の割合が０．１〜２０．０ｍｏｌ％である化粧板１００。化粧板１００は更に、芯材層１２を含む化粧板１００。【選択図】図１
