PROBLEM TO BE SOLVED: To improve the finish quality of a mass of cooked rice.SOLUTION: Each of a pair of rollers 3ac disposed in a rotatable state at the lowermost of a cooked rice measuring and dividing part 3 of a device 1 for molding cooked rice has a surface to come into contact with the mass of cooked rice, on which grooves Gt are intermittently disposed along the axis direction of the roller 3ac. The grooves Gt of the roller 3ac adjacent to each other in the circumferential direction are disposed such that the end positions of the grooves Gt are displaced in the axial direction of the roller 3ac. The roller marks on the surface of the mass of cooked rice after measuring and dividing can be thereby reduced, so that the finish quality of the mass of cooked rice can be improved.
