To smoothly transfer conveying objects at a corner portion.

In this pneumatic conveyor 1, a conveying path 2 is constituted of conveying face plates on which air jetting ports are penetratedly formed in the thickness direction. Turning motion ranges A, B, C for changing the conveyance direction of conveying objects 4 are set on the conveying face plates 9 to 11 and 18 to 24 constituting conveyance direction changing parts 6, 7, 8 on the conveying path 2, and turning entrance parts a, b, c1 that are narrower than half of the turning motion ranges A, B, C are formed in entrance sides of the turning motion ranges A, B, C. The directivity of the air jetting ports 15, 16 formed on the turning entrance parts a, b, c1 is set so as to have smaller angles than those of tangent lines 14a at the points corresponding to the air jetting portions on virtual turning circumferences 14 at the turing entrance parts a, b, c1.
