Abstract
A hot-pressed member is formed using a tailored blank material obtained by butt joining respective ends of two or more coated steel sheets. The hot-pressed member has two or more sites formed by the respective coated steel sheets and at least one joining portion between the sites. Depending on a type of a coated layer of each of the coated steel sheets, t/tis appropriately controlled where tis a thickness of a thinnest portion in the joining portion and tis a thickness of a thinnest site of the sites. A tensile strength of each of the sites is 1180 MPa or more.
