PURPOSE: To obtain flakes of a dried bonito having improved flavor, taste, appearance, etc., by shaving the dried bonito thinly, cutting the resultant shavings into small fragments, filling the shavings in a bag having the airtightness in a given amount, and sealing the bag.

CONSTITUTION: A dried bonito is shaved to a thickness of at least 1mm or less by a motor-driven shaver to prepare shavings of the dried bonito. The resultant shavings are then cut to small fragments of square, rhombic or petalous shape by a cutting means, having U-shaped and comb tooth-like cutting blades, and reciprocating up and down while transferred by a conveyor. The resultant small fragment shavings are transferred to a weighing apparatus by the air suction, and a constant amount of the divided shavings is filled in an airtight bag with nitrogen gas, and sealed. Thus, the rubbing step of shavings with a metallic net, rubbing member, etc. is eliminated to prevent the deterioration of the flavor, taste, etc. thereof by the frictional heat, etc.
