Provided is an intestinal peristaltic sound measurement device, comprising: an abdominal sound acquisition unit for acquiring abdominal sound generated in the abdomen of a subject； a first bandwidth filter for extracting, from intestinal peristaltic sound in a predetermined period acquired by the abdominal sound acquisition unit, a first sound component included in a first frequency bandwidth that is a frequency bandwidth mainly corresponding to intestinal peristaltic sound； a second bandwidth filter for extracting, from the intestinal peristaltic sound in the predetermined period acquired by the abdominal sound acquisition unit, a second sound component included in a second frequency bandwidth having a highest frequency higher than a highest frequency of the first frequency bandwidth； and a dietary intake determination unit for determining whether the subject has taken diet on the basis of a proportion in which an integrated value of sound volume of the second sound component is occupied in a total value of an integrated value of sound volume of the first sound component in a predetermined period extracted by the first bandwidth filter and an integrated value of sound volume of the second sound component in a predetermined period extracted by the second bandwidth filter or on the basis of a comparison result between the integrated value of the first sound component and the second sound component (S8 and S9).L'invention concerne un dispositif de mesure de son péristaltique intestinal, comprenant : une unité d'acquisition de son abdominal pour acquérir un son abdominal généré dans l'abdomen d'un sujet ； un premier filtre de bande passante pour extraire, du son péristaltique intestinal dans une période prédéterminée acquise par l'unité d'acquisition de son abdominal, un premier composant sonore inclus dans une première largeur de bande de fréquence qui est une bande passante de fréquence correspondant principalement au son péristaltique intestinal ； un second filtre d
