A noodle string cutting device of the present invention includes: a pair of cutting blade rolls configured to rotate in opposite directions in an engaged state to cut a dough sheet into noodle strings separating teeth rows contacting outer peripheries of the cutting blade rolls at positions different from each other in rotational directions of the cutting blade rolls and a chute member provided so as to correspond to falling positions of the noodle strings separated by the separating teeth row. Further, the chute member of the noodle string cutting device of the present invention is provided such that two or more sets are formed, each of which includes the adjacent separating teeth rows and in each of which the chute member is provided so as to correspond to the falling positions of the noodle strings separated by one of the adjacent separating teeth rows. With this, the noodle string cutting device can stack the noodle strings on a conveyor such that sticking of the noodle strings in steam-boiling can be reduced, and the noodle strings can be entirely and uniformly gelatinized.
