1. A manufacturing apparatus for an absorbent body comprising:
a first conveyor that conveys an air-permeable first sheet while sucking the first sheet along a flat first slope surface;
a second conveyor that conveys an air-permeable second sheet while sucking the second sheet along a flat second slope surface having a slope opposite to the first slope surface;
a first distribution device that forms a first absorbent layer in the first sheet by distributing absorbent powder on an upper surface of the first sheet being conveyed along the first slope surface;
a second distribution device that forms a second absorbent layer in the second sheet by distributing absorbent powder on an upper surface of the second sheet being conveyed along the second slope surface;
a stacking part that stacks the first sheet conveyed by the first conveyor and the second sheet conveyed by the second conveyor in such a manner as to cause the first absorbent layer of the first sheet and the second absorbent layer of the second sheet to face each other; and
a stacking conveyor, on which a paper being fed, that conveys the first and second sheets and the paper in a state where the paper is disposed under a stack of the first and second sheets stacked together,
the stacking part being a stacking roller that rolls in the first sheet conveyed by the first conveyor and the second sheet conveyed by the second conveyor and stacks the first sheet and the second sheet on each other, and
the stacking conveyor contacting the stacking roller with the stack and the paper therebetween.
