<P>PROBLEM TO BE SOLVED: To obtain a spray distribution measuring method which enables the accurate measurement of the spray distribution of one injection in a short time, and a spray distribution measuring instrument. Ž<P>SOLUTION: The spray distribution measuring method includes: the step of spraying a liquid to be inspected, to which a fluorescent agent is added, to adhere the same to an adhesion member; the step of irradiating the liquid to be inspected adhered to the adhesion member with ultraviolet rays emitted from an exciting light source; the step of measuring the two-dimensional intensity distribution of the fluorescence, which is emitted from the liquid to be inspected adhered to the adhesion member, by a two-dimensional imaging element; and the step of calculating the spray distribution of the liquid to be inspected adhered to the adhesion member using the ultraviolet database being the three-dimensional intensity distribution of the ultraviolet rays emitted from the exciting light source, the database of the adhesion member being the three-dimensional position data of the surface of the adhesion member to which the liquid to be inspected is adhered and the two-dimensional intensity distribution of the fluorescence obtained by the two-dimensional imaging element.
