Abstract: A vacuum chamber 11 for forming a vacuum space has two side walls opposite to each other across an ion beam axis extending within the vacuum space. One of those side walls is openable and closeable. An ion optical element 21 is placed on a base 33, which is located on the bottom surface of the vacuum chamber. A fixation band 213 fixes the ion optical element on the base by holding the element between the base and the fixation band so as to press the element onto the base. A band-catching portion 10d, located on an inside face of a side wall of the vacuum chamber on the opposite side from the openable-and-closeable side wall, catches one end of the fixation band. A band-fixing portion 214, located on the base on the side where the openable-and-closeable side wall is present, fixes the other end of the fixation band to the base.
