Steel sheet for hot pressing use, press-formed product, and method for manufacturing press-formed product

A steel sheet, comprising, in mass %, with respect to a chemical component composition:

• C:
• 0.15-0.5%;
• Si:
• 0.2-3%;
• Mn:
• 0.5-3%;
• P:
• 0.05% or less, exclusive of 0%;
• S:
• 0.05% or less, exclusive of 0%;
• Al:
• 0.01-1%;
• B:
• 0.0002-0.01%;
• Ti:
• 3.4[N]+0.01% or more and 3.4[N]+0.1% or less, wherein [N] represents N content in mass %;
• and
• N:
• 0.001-0.01% respectively, with a remainder comprising iron and inevitable impurities, wherein
• some of Ti-containing precipitates contained in the steel sheet, each of which having an equivalent circle diameter of 30 nm or less, have an average equivalent circle diameter of 3 nm or more, a precipitated Ti amount and a total Ti amount in the steel fulfill a relationship of formula (1), and a sum total of a fraction of bainite and a fraction of martensite in a metal microstructure is 80 area % or more:
• precipitated Ti amount (mass %)−3.4[N]>0.5×[(total Ti amount (mass %))−3.4[N]] (1)
• wherein [N] represents the content (mass %) of N in the steel.
