The subject of the instant disclosure is to increase the practicality or the planting precision. Disclosed is a seedling transplanter. The seedling transplanter comprises a running device, a seed transportation part to transport seeds, and a seed planting device (6) to plant the seeds in farm, wherein the seeds are transported to the planting supply position (A) by the seed transportation part. The seed transportation part comprises: an upper lateral transmitting part (5a) transmitting the seeds towards the right or the left, a descending transmitting part following the upper lateral transmitting part (5a) for transmitting the seeds to the planting supply position (A) below, and an uplifting transmitting part following the descending transmitting part for transmitting the seeds towards the transportation starting side of the upper lateral transmitting part (5a) located outside and above the left and right direction of the main body. The seed transportation part is configured to be deviated toward the right side or the left side of the transportation starting side for the upper lateral transmitting part (5a). The seed planting device (6) uses a pair of seed planting holders, the left one and the right one, to hold the seed at the planting supply position (A), operate in a given route and then plant the seed in farm. A liquid tank (124) is configured to contain liquid and to be deviated toward the left and right side opposite to the seed transportation part. A liquid discharge port is provided only on the seed planting holder at the side deviated toward the seed transportation part. The liquid discharge port discharges the liquid to the farm at the position where the holder is or near the holder.本發明的課題係提高作業性或栽種精度。本發明為一種苗移植機，係具備有：行駛裝置；苗搬送部，用以搬送苗；以及苗栽種裝置(6)，將由苗搬送部搬送到栽種供給位置(A)的苗栽種在農田中；苗搬送部係具備：上部橫向輸送部(5a)，朝左右橫向搬送苗；下降輸送部，與上部橫向輸送部(5a)接續且朝下方的栽種供給位置(A)搬送苗；以及上升輸送部，與下降輸送部接續且朝機體的左右方向外側且成為上側的上部橫向輸送部(5a)的搬送開始端側搬送苗；且朝成為上部橫向輸送部(5a)的搬送開始端側的左右一側偏移地配置；苗栽種裝置(6)係由左右一對的苗栽種夾持工具夾持栽種
