To prevent damage on a slice or disarrangement of alignment when a frozen food F is sliced.

This frozen food slicer includes a cutter 1 with a plurality of disc saws disposed in a line at prescribed intervals in which the thickness of the disc saws 12 at both ends of the line is set to be thicker appropriately than that in the central part side, a table 4 with a slit for protruding the upper part of the disc saws 12 from the surface of the table so that the frozen food F placed on the surface of the table can be sliced, and a pusher 2 moved forwards and backwards relative to the cutter 1, which is contacted with the frozen food F placed on the table 4 when moved forwards toward the cutter 1 to push and feed the frozen food F to the cutter 1 to be sliced and pushed out therefrom, and then moved backwards.
