[Problem] To provide a device for automatically opening the ovarian membrane of salmon roe, the device capable of automatically and continuously opening the ovarian membranes of salmon roe without injuring roe granules.[Solution] The present invention is configured from: a transfer unit (9) which has a transfer region (8) for transferring salmon roe (100) from an input region (4) to a discharge region (6) and has an opening (17) at a predetermined position of the transfer region (8) a membrane attraction unit (24) which is disposed below the transfer unit and provided with a suction port facing the opening and attracts the ovarian membrane (101) of the transferred salmon roe from the opening and a membrane split unit (30) which protrudes above a transfer surface (14) from the opening provided in the transfer unit and splits the ovarian membrane of the salmon roe attracted by the membrane attraction unit. The membrane split unit includes a membrane sticking part (41) which protrudes above the transfer surface from the opening, and a membrane split blade (44) which is continuous with the membrane sticking part and is provided closer to the opening than the membrane sticking part, and the membrane attraction unit has the suction port (28) immediately below the tip of the membrane sticking part.[Problème] Linvention concerne un dispositif douverture automatique de la membrane ovarienne dœufs de saumon, le dispositif étant capable douvrir automatiquement et en continu les membranes ovariennes dœufs de saumon sans endommager les granules dœufs.[Solution] La présente invention est constituée : dune unité (9) de transfert comportant une région (8) de transfert servant à transférer des œufs (100) de saumon dune région (4) dentrée à une région (6) dévacuation et présentant une ouverture (17) à une position prédéterminée de la région (8) de transfert dune unité (24) dattraction de membrane, qui est disposée au-dessous de lunité de transfert et munie dun orifice daspiration fa
