프레스 성형품(10)은, 양단에 각각 제1 단부(11a) 및 제2 단부(11b)를 갖는 본체부(11)와, 본체부(11)의 만곡부로부터 만곡의 외측으로 돌출하는 돌기부(12)를 포함한다. 본체부(11)의 천판부(13a)의 표면에는, 돌기부(12)의 근원으로부터 제1 단부(11a)측의 영역에 홈부(15)가 설치된다. 본체부(11)의 제1 단부(11a)로부터 돌기부(12)에 이르는 제1 종벽부(14a)는, 본체부(11)와 돌기부(12)를 연결하는 코너부(16)를 갖는다. 코너부(16)로부터 본체부(11)측이 되는 부분과 코너부(16)로부터 돌기부(12)측이 되는 부분이 이루는 각도가 예각이다. 프레스 성형품(10)의 제조 방법은, 천판부(13a)의 표면 형상 중에서 홈부(15)의 형상을 성형하지 않고, 또한 제1 종벽부(14a)를 성형하는 제1 공정과, 천판부(13a)의 표면 형상 중에서 홈부(15)의 형상을 성형하는 제2 공정을 포함한다.

    A press-formed product (10) includes a main body part (11) having a first end part (11a) and a second end part (11b) respectively on both ends, and a protruded part (12) that protrudes outward of bending from a bent part of the main body part (11). On a surface of the top plate part (13a) of the main body part (11), a groove part (15) is provided in a domain on the first end part (11a) side from a root of the protruded part (12). A first vertical wall part (14a) extending from the first end part (11a) of the main body part (11) to the protruded part (12) has a corner part (16) connecting the main body part (11) and the protruded part (12). An angle that is formed by a part which is on the main body part (11) side from the corner part (16) and a part which is on the protruded part (12) side from the corner part (16) is an acute angle. A method for producing the press-formed product (10) includes a first step of forming the first vertical wall part (14a) without forming a shape of the groove part (15) in a surface shape of the top plate part (13a), and a second step of forming the shape of the groove part (15) in the surface shape of the top plate part (13a).
