PROBLEM TO BE SOLVED: To provide a steel sheet for hot pressing which, when a uniform characteristic is required in a molded product, can yield a hot-press molded product capable of achieving a balance between high strength and elongation at a high level and, when regions corresponding to an impact-resistant part and an energy-absorbing part are required in a single molded product, is useful for obtaining a hot-press molded product capable of achieving a balance between high strength and elongation corresponding to each region at a high level.SOLUTION: A steel sheet for hot pressing has a prescribed chemical composition, wherein the average circle equivalent diameter of Ti-containing precipitates contained in the steel sheet having a circle equivalent diameter of ≤30 nm is ≥3 nm, the precipitated Ti content and the total Ti content in the steel satisfy the following relation (1): (precipitated Ti content (mass%))-3.4[N]>0.5×[(total Ti content (mass%))-3.4[N]] (wherein [N] is the N content (mass%) in the steel), and the total area fraction of bainite and martensite in the metallic structure is ≥80%. |
