1. An ion analyzer configured to control movement of ions flowing out from an ion outflow port, the ion analyzer comprising:
a base member fixed to the ion outflow port and having a cylindrical concave part;
a first conductive member having conductivity and being a cylindrical member accommodated in the concave part, one end of the first conductive member being exposed and a first ion flow controller configured to control movement of the ions being fixed to the one end of the first conductive member;
an insulating member being a cylindrical member inserted into the first conductive member;
a second conductive member having conductivity and being a rod-shaped member inserted into the insulating member, one end of the second conductive member being exposed and a second ion flow controller configured to control movement of the ions being fixed to the one end of the second conductive member;
a first power feeding unit provided on the base member and to which a first predetermined voltage is applied, the first power feeding unit being provided at a position where the first conductive member comes into contact with the first power feeding unit in a state of being accommodated in the concave part; and
a second power feeding unit provided on the base member and to which a second predetermined voltage is applied, the second power feeding unit being provided at a position where the second conductive member comes into contact with the second power feeding unit in a state where the first conductive member accommodating the second conductive member and the insulating member is accommodated in the concave part.
