Abstract
A transfer electrode unit () is configured by coaxially arranging a plurality of loop electrodes (A,B,C), and guides ions to an orthogonal acceleration region (C) by allowing the ions to pass through an inner side of the plurality of electrodes (A,B,C) each of which is applied with a voltage. A voltage having a higher absolute value than the voltage applied to the plurality of electrodes (A,B,C) is applied to a flight tube (), and the ions accelerated in the orthogonal acceleration region (C) are introduced to a flight space formed in the flight tube (). A shield portion (F) is provided between the transfer electrode unit () and the flight tube (), and suppresses that an electric field derived from the voltage applied to the flight tube () enters the transfer electrode unit ().
