판재 조각들을 적절하게 일치시킬 수 있으며, 판재 조각들을 적절하게 일치할 수 있는 경우에 있어서도 제품의 중량을 무겁게 하게 않는 프레스 성형품 및 그의 제조 방법을 제공한다. 본 발명은 블랭크재 B를 절곡함으로써, 블랭크재를 절곡부를 사이에 두고 제1 판재 조각(10)과 제2 판재조각(20)으로 분할하며, 절곡함으로써 제1 판재조각과 제2 판재조각을 당접시켜서 형성한 프레스 성형품(100)에 있어서, 제1 판재조각 및 제2 판재조각은 블랭크재를 펀칭하여 형성한 펀칭부(11), (21)과, 펀칭부의 연부를 상승하여 형성한 제1 상승부(12) 및 제2 상승부(22)를 가지며, 제1 판재조각의 제1 상승부와 제2 판재조각의 제2 상승부를 계합시킴으로써 제1 판재조각과 제2 판재조각을 위치 결정하는 위치 결정부(40)가 마련된다.

    [Object] Provided are a press-molded product in which the plank pieces can be appropriately matched with each other and the weight of the product is not increased even when the plank pieces can be appropriately matched with each other, and a method of manufacturing the same. [Solving Means] The present invention is a press-molded product (100) formed by bending a blank (B) to divide the blank into a first plank piece (10) and a second plank piece (20) with a bending portion interposed therebetween and making the first plank piece and the second plank piece come into contact with each other through the bending. The first plank piece and the second plank piece include punching portions (11, 21) formed by punching the blank, and a first rising portion (12) and a second rising portion (22) formed by raising the rims of the punching portions. There is provided a positioning portion (40) that positions the first plank piece and the second plank piece by engaging the first rising portion of the first plank piece with the second rising portion of the second plank piece.
