A floor board for salt farm of the present invention comprises: a board of a plate form with multiple sides; an inserting projection part which protrudes from at least two sides among the sides of the board; an inserted groove part which is formed at the remaining side among the sides of the board except for the sides in which the inserting projection part is formed; and a partition part which is installed at the bottom surface of the board in order to prevent the distortion of the board and forms a space part in which the bottom materials of salt farm are filled. The floor board is formed in a method in which a connection structure of the boards is formed in a method which inserts and fits the boards in a concavo-convex form, thereby minimizing the inflow of foreign substances into the gap between the boards or the leak of salt water, strengthening the connection structure of the boards and prevents a gap from being generated between boards when the floor board is used for a long time. |
