Zusammenfassung:	A press forming tool includes: a punch; and a die, and press forms a press forming product including a punch bottom and a shallow concave portion or a low convex portion in the punch bottom. The punch includes a punch bottom forming surface, a concave shape forming portion or a convex shape forming portion, and a low Young's modulus member installation region formed under the punch bottom forming surface and accommodating a low Young's modulus member having a lower Young's modulus than that of the punch bottom forming surface. The low Young's modulus member installation region includes an area directly under the concave shape forming portion or the convex shape forming portion of the punch and has a projected area in a press forming direction that is 110% or greater as large as a projected area of the concave shape forming portion or the convex shape forming portion.
