A noncontact type tonometer capable of accurately measuring intraocular pressure of a subject's eye even if the intraocular pressure is much higher than normal. The noncontact type tonometer comprises a fluid discharging device for discharging fluid toward a cornea of the eye, a corneal transfiguration detecting portion for detecting the corneal transfiguration, a pressure detecting portion for detecting discharge pressure of the fluid, and a delay circuit for determining the precise moment for stopping the operation of the fluid discharging means according to the discharge pressure detected by the pressure detecting means.
