Provided are a protrusion molding device, a protrusion molding method, and a molded article, with which a height equal to or greater than the plate thickness is possible, the edges are sharp, and cracking can be prevented. This protrusion molding device (1) is characterized by being equipped with a die unit (12) provided with a die hole (12a), and a punch unit (40) having a large punch part (41) with a size such that this part cannot be inserted into the die hole (12a), and a small punch part (42) that protrudes from the large punch part (41) toward the die unit (12) and can be inserted into the die hole (12a), and characterized in that the workpiece (W) is deformed by pressing a portion of the workpiece arranged between the die unit (12) and the punch unit (40) toward the die unit (12) by means of the punch unit (40), thereby forming a protrusion (W1). |
