Recent advances in the structural study of liquids under high pressure are reviewed. Using x-rays from synchrotron radiation with high energy and high brightness, x-ray diffraction measurements have been successfully performed for various liquids. Differences in the pressure dependences of the structure are discussed between typical liquid metals, such as alkali metals, and liquids in which atoms are bonded covalently.
