An object of the present invention is to provide a steel sheet, a member, and a method for producing the same, which are excellent in cold workability, hardenability, and surface hardness after quenching. The steel sheet of the present invention has a predetermined composition and a microstructure including ferrite and carbide, the volume ratio of ferrite and carbide in the entire microstructure is 90% or more, and the proeutectoid ferrite is in the microstructure. The volume ratio of the whole structure is 20% to 80%, the Mn concentration in the carbide is 0.10% by mass to 0.50% by mass, and the number of carbides with a particle size of 1 μm or more in the total number of carbides is: 30% to 60%. |
