    Disclosed is a press formed product (100) which is formed from a single steel sheet (101). The press formed product (100) includes two vertical wall portions (111), a top plate portion (112) which connects two vertical wall portions (111) with each other, and a projecting portion (115) which projects from at least one boundary portion of two boundary portions each of which connects the vertical wall portion (111) and the top plate portion (112) with each other. In the projecting portion (115), a steel sheet (101a) extending from the vertical wall portion (111) and a steel sheet (101b) extending from the top plate portion (112) project from the boundary portion so as to overlap at an overlapping portion (115d) located at least at a distal end of the projecting portion (115). The projecting portion (115) is present at least at a portion of the press formed product (100) in a longitudinal direction. An angle (X) formed between the top plate portion (112) and the overlapping portion (115d) is larger than 180°.
