PROBLEM TO BE SOLVED: To provide a seeding device capable of improving workability when exchanging a suction plate and increasing the degree of freedom of a hole drilling position of a suction hole. SOLUTION: The width of a support member 3a4 of a suction device 3 is formed to be smaller than the diameter of an inner hole 3c2 of a suction hole 3c. Therefore, even if the suction holes 3c and the support member 3a4 overlap each other and the support member 3a4 comes into contact with the inner hole 3c2 of the suction hole 3c, the inner hole 3c2 is not closed by the support member 3a4. That is, no matter where the suction hole 3c is drilled in the suction plate 3b, the negative pressure from the suction device is applied to the suction hole 3c, and the seed S can be sucked into the suction hole 3c. As a result, when replacing the suction plate 3b, it is not necessary to consider the positional relationship between the suction hole 3c and the support member 3a4, so that the workability when replacing the suction plate 3b can be improved and the suction plate 3b can be replaced. The degree of freedom of the drilling position of the suction hole 3c in the plate 3b can be increased. [Selection diagram] Fig. 3【課題】吸着板を交換する際の作業性を向上できると共に、吸着穴の穿孔位置の自由度を高くできる播種装置を提供すること。【解決手段】吸着装置３の支持部材３ａ４の幅は、吸着穴３ｃの内側穴３ｃ２の径よりも小さく形成される。従って、吸着穴３ｃと、支持部材３ａ４との位置が重なり、支持部材３ａ４が吸着穴３ｃの内側穴３ｃ２に当接しても、支持部材３ａ４によって内側穴３ｃ２が閉塞されない。即ち吸着板３ｂのいずれの位置に吸着穴３ｃを穿孔しても、吸引装置からの負圧が吸着穴３ｃに付与され、吸着穴３ｃに種子Ｓを吸着できる。これにより、吸着板３ｂを交換する場合に、吸着穴３ｃと支持部材３ａ４との位置関係を考慮する必要がないので、吸着板３ｂを交換する際の作業性を向上させることができると共に、吸着板３ｂへの吸着穴３ｃの穿孔位置の自由度も高くできる。【選択図】図３
