PROBLEM TO BE SOLVED: To provide a radiographic method capable of performing a radiography while suppressing the increase of a magnification factor in the radiography performed by using a ray source of a small focus and by making a screen and subject away from each other. SOLUTION: The radiographic method for obtaining detection signals by detecting the intensity of radiation transmitted through the subject comprises: a step (a) of generating the radiation from a radiation source having a focus size of 100μm or less; a step (b) of narrowing the spreading angle of the radiation by making the radiation generated from the radiation source be incident on a capillary lens; and a step (c) for irradiating the object with the radiation emitted from the capillary lens and detecting the intensity of the radiation transmitted through the subject by a detection means.
