PROBLEM TO BE SOLVED: To provide an agitation blade unit singly capable of appropriately effecting agitation movement in the reciprocating direction along a rotary main shaft and thereby causing a good agitation effect. SOLUTION: This agitation blade unit consists of a rotary main shaft 1 and a plurality of blade members 2 each fixed to the rotary main shaft 1, wherein each of the blade members 2 consists of a pair of blade sub-members 2a and 2b both of which are fixed to the rotary main shaft 1 so that they are placed on a straight line while holding the rotary main shaft 1 between them; each of the blade sub-members 2a and 2b consists of blade sub-member sections 2a1 and 2a2, or 2b1 and 2b2; each of the blade sub-member sections 2a1, 2a2, 2b1 and 2b2, when viewed from the side of its one end, has the same inclination in relation to a plane orthogonally intersecting the rotary main shaft 1, as those of the others; and the plurality of blade members 2 each in such a state, are arranged on the rotary main shaft 1 in its longitudinal direction from the center toward the both ends of the shaft 1, at intervals of a prescribed distance from the blade member 2 positioned at the center of the shaft, and also, at intervals of a 120 deg. inclination in relation to this blade member 2.
