PROBLEM TO BE SOLVED: To provide a non-contact tonometer suppressing hindering, by the eyelash, of flow of air blown onto the cornea from an air flow blowing nozzle.SOLUTION: The non-contact tonometer includes: an air flow blowing nozzle 8 provided coaxially with the optical axis O1 of the anterior ocular segment observation optical system and moved away from and to an eye to be tested E, and blows the air flow onto the cornea C an upper fixation mark optical system 60 showing the fixation mark to the eye to be tested E and an arithmetic circuit 81 computing an intraocular pressure value based on detection information accompanying the deformation of the cornea C when the air flow is sprayed on the eye to be tested E. The relative position of the air flow blowing nozzle 8 and the upper fixation mark optical system 60 is set so that the air flow blowing nozzle 8 blows the air flow from the bottom with respect to the view axis when the eye to be tested E performs fixation of the upper fixation mark.
