The device for predicting crack generation in dry noodles is equipped with: a light source that irradiates polarized light on the dry noodles an image pickup unit that acquires a phase difference image of the dry noodles based on the light passing through the dry noodles as a result of the polarized light irradiated from the light source and a predicting unit that measures the birefringence phase difference of the dry noodles based on the phase difference image acquired by the image pickup unit and evaluates the residual stress in the dry noodles from the measured birefringence phase difference to predict whether or not cracks will occur in the dry noodles.
