An absorbent sheet manufacturing apparatus has a particle collision surface (224) that extends downward from a cylinder outer surface (211) in between the lowermost part of a supply cylinder (21) and a second sheet conveying roller (41). Some of the particles emitted forward in the rotation direction of the supply cylinder (21) from recessed supply portions (212) that have passed a first cover part (221) collide with the particle collision surface (224), and the colliding particles are guided by the particle collision surface (224) onto a first sheet member (91). This suppresses direct collision of particles emitted from the supply cylinder (21) with a second sheet member (92) on the second sheet conveying roller (41). Scattering of particles that have collided with the second sheet member (92) around the first sheet member (91) and the second sheet member (92) is thus suppressed.
