PROBLEM TO BE SOLVED: To enable measurement with high accuracy at fuel volume measuring for each of nozzle holes. SOLUTION: This device measures individually a volume of fluid F injected from each of the nozzle holes 4 of a multi-port fuel injection nozzle 1. In this device, the nozzle holes 4 respectively comprises: fluid pipes 12; containers 13; and three-way valves 17, and a switching means 18 is provided for simultaneously switching each of the three-way valves 17 to one side or the other side. Since all of the three-way valves 17 are simultaneously switched and an operation of storing the fluid to the containers 13 is performed, the measurement under the same measuring condition is enabled, whereby measuring accuracy is considerably enhanced. An initial weight before fluid storing and a weight after fluid storing are individually measured by each of weight measuring devices 16, and based on a difference between the initial weight and the weight after fluid storing, an injection volume dispersion in each of the nozzle holes is evaluated.
