Disclosed is a method of manufacturing an intraocular pressure sensor that is put into an eyeball of a patient and measures the intraocular pressure, the method comprising: preparing a first substrate; depositing a base film on the bottom of the first substrate; exposing the top of the base film by etching the first substrate; applying epoxy onto the center of the exposed base film; disposing the first electrode at the epoxy-applied portion on the base film; preparing a second substrate; depositing a support film onto the second substrate; forming a second electrode on the support film; exposing the bottom of the support film by etching the second substrate; and disposing the second substrate onto the first substrate.
