The present invention provides a contact lens sterilizing device which can sufficiently sterilize contact lenses (13). The contact lens sterilizing device comprises: a treatment tank (35) which accommodates a first medium and is provided with a vibration transmission part in the lower section thereof a lens case (11) which is detachably disposed in the treatment tank (35) and mountably disposed on the vibration transmission part, and which accommodates the contact lenses (13) and a second medium an ultrasonic vibrator (22) for generating ultrasonic vibrations and transmitting the ultrasonic vibrations to the vibration transmission part and an ultrasonic vibrator driving means (22) for driving the ultrasonic vibrator (22) to thereby produce hydroxyl radicals in the second medium. The contact lenses (13) can be sufficiently sterilized as a result of the ultrasonic vibrator (22) being driven to thereby produce hydroxyl radicals in the second medium. In addition, it is possible to simplify the sterilizing process since the contact lenses (13) can be sterilized in an extremely short amount of time without having to neutralize a processing liquid after sterilizing has finished.La présente invention concerne un dispositif de stérilisation de lentilles de contact qui peut stériliser suffisamment des lentilles de contact (13). Le dispositif de stérilisation de lentilles de contact comprend : une cuve de traitement (35) qui reçoit un premier milieu et est pourvue dune partie de transmission de vibration dans la section inférieure de celle-ci un étui à lentilles (11) qui est disposé de façon détachable dans la cuve de traitement (35) et disposé de façon montable sur la partie de transmission de vibration, et qui reçoit les lentilles de contact (13) et un deuxième milieu un vibreur ultrasonore (22) pour générer des vibrations ultrasonores et transmettre les vibrations ultrasonores à la partie de transmission de vibration et des moyens dexcitation de vibreur ultrasonore (22)
