摘要
Provided is a steel sheet for a hot press formed member having excellent painting adhesion and post-painting corrosion resistance, and a method for manufacturing the same. A steel sheet for hot press forming according to one aspect of the present invention comprises a base steel sheet and a plated layer formed on a surface of the base steel sheet, wherein the ratio of an area occupied by pores to the entire area of a surface layer portion may be 10% or more in a cross section of the surface layer portion observed when the plated layer is cut in a thickness direction thereof.
