1. A method for displaying/analyzing a body fluid absorption mode of an absorbent article comprising the steps of: in a state in which an absorbent article is put on a human body type dummy doll equipped with a body fluid-supplying means, photographing the absorbent article after the fluid is excreted from the dummy doll by an X-ray CT apparatus; and displaying/analyzing, based on the photographed image, the change with time of the absorption and diffusion state of the drainage into the absorbent article after the excretion in the state in which the absorbent article is put on the dummy doll, wherein: the dummy doll is set on a bed which can move forward toward a photographing position of the X-ray CT apparatus; after the bed is put into the photographing position, an X-ray source and a detector of the X-ray CT apparatus are turned around the dummy doll, while the body fluid-supplying means is driven to inject artificial urine into the dummy doll; the artificial urine supplied by the body fluid-supplying means is passed through a path formed in the human body type dummy doll and drains from a private part of the dummy doll; the change with time of the absorption and diffusion of the artificial urine in an absorbent article is measured by the X-ray CT apparatus; and the absorbent article and the artificial urine is only displayed by using a window function of the X-ray CT apparatus.
