A simple and economic apparatus for crystal growth effective in crystallization of a biological macromolecule such as protein is provided. The apparatus for crystal growth includes first liquid storage parts and for holding a liquid to be used for crystal growth, passages and for transporting the liquid from the first liquid storage parts and to other places, and a second liquid storage part for receiving the liquid transported by the passages and. The first liquid storage parts and are formed on a substrate formed of a general-purpose material such as glass. The second liquid storage part is formed on a doped silicon substrate. Crystal growth occurs on the surface of the silicon substrate having a certain electric state.
