PURPOSE:To produce a rice cake, snack food, etc., having soft feeling to the tooth, in a short time, by expanding a raw material containing rice flour and an oil fat as essential components with a multi-screw extruder. CONSTITUTION:Rice flour such as nonglutinous rice flour, glutinous rice flour, etc., finer than 60 mesh and an oil or fat or a W/O-type emulsion etc., are used as essential components, and optionally added with tasty foods, seasonings, etc. The amount of the oil or fat is 6-35wt%, preferably 10-30wt% based on the raw material. The raw material mixture is expanded by using a multi- screw extruder, preferably a twin-screw extruder, especially a twin-screw extruder having trapezoidal thread contour.
