PROBLEM TO BE SOLVED: To provide a food cutting device capable of continuously performing cutting process of putting a plurality of cuts into only a boiled fish cake out of the cake with a plate, at one time at a prescribed interval in a transportation passage with a belt conveyor.SOLUTION: A food cutting device is installed in the middle of a belt conveyor transportation passage, and simultaneously forms a plurality of cuts on a processed food by rotationally driving a plurality of disk-like rotary blades having the same diameter in the same direction as a transportation direction and at a peripheral end speed higher than a belt conveyor transportation speed, the rotary blades being coaxially fixed at an equal interval and in parallel with each other to a central roll extending in a direction orthogonal to the transportation direction. A belt conveyor extending along the transportation passage including from a cutting starting point of the food to a cutting end point thereof has a belt surface which allows t
