A portable X-ray diffraction apparatus is provided which can be held by a person and on which an image of a spot to be measured can be viewed. The portable X-ray diffraction apparatus includes: X-ray irradiation means that irradiates a sample with collimated X-rays; diffracted X-ray detection means that detects a collimated portion of diffracted X-rays among X-rays diffracted from the sample by the irradiation of the X-rays with the X-ray irradiation means; and signal processing means that processes a signal outputted from the diffracted X-ray detection means. An X-ray diffraction method is used which includes: irradiating a sample with collimated continuous-wavelength X-rays; extracting a collimated portion of diffracted X-rays diffracted from the sample irradiated with the X-rays and condensing the extracted collimated portion of the diffracted X-rays; detecting, using an energy dispersive detection element, the condensed diffracted X-rays; and processing a signal detected by the detection element. |
