To provide a method for efficiently obtaining metal phenoxide from decomposition products of thermosetting resins, which contain a variety of substances in addition to the thermosetting resin, such as epoxy resin.SOLUTION: A method for producing metal phenoxide includes following steps A-C. Step A: decomposing a thermosetting cured resin to produce a decomposition liquid A containing metal phenoxide. Step B: adding water to the decomposition liquid A obtained in the step A, to produce an oil-water two-phase liquid B. Step C: separating the oil-water two-phase liquid B obtained in the step B to oil and water, thereby recovering metal phenoxide.SELECTED DRAWING: None 【課題】エポキシ樹脂等の熱硬化性樹脂以外に様々な生成物を含んだ熱硬化性樹脂分解物から、効率よく金属フェノキシドを得る方法を提供する。【解決手段】以下の工程Ａ～工程Ｃを含む、金属フェノキシドの製造方法。工程Ａ：熱硬化性樹脂硬化物を分解し、金属フェノキシドを含む分解液Ａを得る工程工程Ｂ：工程Ａで得られた分解液Ａに水を加え、油水２相液Ｂを得る工程工程Ｃ：工程Ｂで得られた油水２相液Ｂを油水分離し、金属フェノキシドを得る工程【選択図】なし
