PROBLEM TO BE SOLVED: To provide a paddy field working machine which has a sowing device and a fertilizing device in a state arranged in the longitudinal direction in a working portion, thereby simplifying the configuration, and which can well sow seeds in a state not scattering seeds in the lateral direction, even when sowing seeds spacedly. ! SOLUTION: In the paddy field working machine, a working portion (A) is connected to the rear portion of a travel machine frame 3 through a link mechanisms 5 in a state capable of being lifted or lowered and has the sowing device 9 and the fertilizing device 10 in a state arranged in the longitudinal direction, and the sowing device 9 and the fertilizing device 10 are arranged in a state that the upper end portion of a fertilizer-storing portion 56 in the fertilizing device 10 is placed below the upper end portion of a seed-storing portion 27 in the sowing device 9. !
