PROBLEM TO BE SOLVED: To provide an electrical stimulation device and method which are minimally invasive to a patient when electrical stimulation is applied to a retina and are free from the risk of corneal damage. An apparatus for applying electrical stimulation to the retina includes a skin electrode 20 including an electrode 21 for the right eye, an electrode 22 for the left eye, and an electrode 23 for common use, and the electrode 21 for the right eye is provided. A current between the common electrode 23 and the common electrode 23 to electrically stimulate the retina of the right eye, and a current between the left electrode 22 and the common electrode 23 to stimulate the left eye retina. Configured to give. Further, a method for applying electrical stimulation to the retina, which is performed by a device including a skin electrode 20 including an electrode 21 for the right eye, an electrode 22 for the left eye, and an electrode 23 for common use, is Of applying a current between the electrode 21 and the common electrode 23 of the left eye to apply electrical stimulation to the retina of the right eye, and applying a current between the electrode 22 for the left eye and the common electrode 23 of the left eye Applying electrical stimulation to the retina. [Selection diagram] Figure 2【課題】網膜に電気刺激を与えるにあたって、患者に対して低侵襲であり、角膜障害の危険性のない、電気刺激装置および方法を提供する。【解決手段】網膜に電気刺激を与えるための装置は、右眼用の電極２１と、左眼用の電極２２と、共用の電極２３とからなる皮膚電極２０を備え、右眼用の電極２１と共用の電極２３との間に電流を流して右眼の網膜に電気刺激を与え、左眼用の電極２２と共用の電極２３との間に電流を流して左眼の網膜に電気刺激を与えるように構成される。また、右眼用の電極２１と、左眼用の電極２２と、共用の電極２３とからなる皮膚電極２０を備えた装置によって行われる、網膜に電気刺激を与えるための方法は、右眼用の電極２１と共用の電極２３との間に電流を流して右眼の網膜に電気刺激を与えるステップと、左眼用の電極２２と共用の電極２３との間に電流を流して左眼の網膜に電気刺激を与えるステップとを含む。【選択図】図２
