PROBLEM TO BE SOLVED: To provide an X-ray diagnostic apparatus capable of improving inspection efficiency.SOLUTION: An X-ray tube 7 generates X-rays. An X-ray detector 10 detects the X-rays generated from the X-ray tube 7. A placing surface 11 is held between the X-ray tube 7 and the X-ray detector 10, and includes a placing part for a subject and a placing part for a sample collected from the subject. A placing table supporting mechanism 3 supports the X-ray detector 10 and the placing surface 11. An X-ray tube supporting mechanism 4 turnably supports the X-ray tube 7 around a prescribed rotational axis. An exposure field limiting device 33 limits a solid angle of the X-rays generated from the X-ray tube 7. An imaging control part 29 controls the X-ray tube supporting mechanism 4 and the exposure field limiting device 33 and thereby selectively switches an exposure field of the X-rays generated from the X-ray tube 7 in the placing surface 11 between the placing part for the subject and the placing part for the sample each on the placing surface 11.
