Provided is a kneaded dough dividing apparatus including a divider having a single dough inlet receiving kneaded dough and two dough outlets for discharging the received kneaded dough as two streams of kneaded dough. The apparatus includes a dough supply pipe continuously supplying kneaded dough to the dough inlet of the divider, and a pressure distribution changing plate provided in the dough supply pipe. The pressure distribution changing plate having a width in a direction traversing a cross-section of the dough supply pipe as seen in the cross-section and a length extending from an upstream end to downstream end of the pressure distribution changing plate. The pressure distribution changing plate is twisted so that a direction of the width at the downstream end is generally at a right angle to a direction of the width at the upstream end.
