The present invention provides an evaluation method of a corneal disorder that can measure a disorder of a cornea quantitatively and is applicable to living eyes. A method for measuring a corneal transepithelial electric resistance comprises placing electrodes on the cornea and a conjunctiva. The method for measuring a corneal transepithelial electric resistance comprises: (1) a step of placing a first electrode on the cornea and a second electrode on the conjunctiva and (2) a step of flowing an electric current between the first electrode and the second electrode to measure the electric resistance. And a device for measuring a corneal transepithelial electric resistance value.
