An edge of a pressing target is suppressed from cracking. A roll press apparatus 100 has a roller 30 that presses a pressing target M. The roller 30 includes a first roller part 31 that presses the pressing target M in a radial direction of the roller 30 and a second roller part 32 that protrudes further than the first roller part 31 in the radial direction on each side of the first roller part 31 in an axial direction of the roller 30 to make contact with the pressing target M in the axial direction. Each of the second roller parts 32 has an elastic member E2 at least in a portion in contact with the pressing target M.
