Provided is a method of producing various 2-((meth)allyloxymethyl)acrylic acid derivatives in high yields with no need to load a raw material in a large excess for improving a reaction conversion ratio, and without use of a catalyst having high toxicity or a strong acid catalyst. Also provided are powder compounds that may be utilized as raw materials for synthesizing various chemical products. A method of producing a 2-((meth)allyloxymethyl)acrylic acid derivative includes causing the powder of a salt of a 2-((meth)allyloxymethyl)acrylic acid anion and an alkali metal cation (component A), and a halide (component B) to react with each other to produce a 2-((meth)allyloxymethyl)acrylic acid derivative. The 2-((meth)allyloxymethyl)acrylic acid alkali metal salt powder is the powder of a salt of a 2-((meth)allyloxymethyl)acrylic acid anion and an alkali metal cation, and has a bulk density of 0.50 g/mL or more, or a water content of 0.05 wt % or less.
