As is apparent from the above examples, the present invention is a sowing apparatus for sowing seeds (74) by adsorbing the seeds (74) on the peripheral surface of the sowing roll (24). Of the seeds (74) of the seeding roll (24) is released and the seeds are released from the seeding roll (24) by supplying water, and thus the seeds (74) are dropped, for example. The seeds (74) can also be reliably dropped to a predetermined position than before, and the seeding roll (24) can be rotated at a higher speed than before, so that the seeding function and the work efficiency are improved as compared with the conventional one. The above can be easily achieved.
