PROBLEM TO BE SOLVED: To provide a press-forming method with which even a press-formed product which is difficult to form need not be divided into a plurality of pieces to facilitate the forming, and the pressed article can be easily formed by performing the working of a small number of steps on one plate without occurring thickness reduction, any cracks, neck or wrinkles at a very favorable cost, and to provide a press-formed product. SOLUTION: Channel parts C<SB>1</SB>and C<SB>2</SB>are formed from one side edge 3b to the other side edge 3b so that a flat base plate 3 forms a hat channel section. When press-formed products W<SB>1</SB>and W<SB>2</SB>folded around a folding line 2 orthogonal to the axes of the channel parts C<SB>1</SB>and C<SB>2</SB>are press-formed, contours of the products W<SB>1</SB>and W<SB>2</SB>are pulled in the direction orthogonal to the longitudinal axes of the channel parts C<SB>1</SB>and C<SB>2</SB>, and preliminarily press-formed products Wa and Wb of the shape corresponding to the shape obtained by the folding so that flat parts 4a and 4b of the base plate 3 are brought close to each other around the folding line 2 are preliminarily formed, and pressed against the die of the final shape.
