Abstract
An undulator magnet having favorable transportation workability is provided. Specifically, an undulator permanent magnet used for an undulator is provided that generates radiation light by meandering electrons that travel in a first direction, wherein, in the undulator permanent magnet, one end surface in the first direction forms a first connecting surface connected to another undulator permanent magnet, N poles and S poles are alternately arranged in the first direction on one magnetic pole surface in a second direction orthogonal to the first direction, and thus a magnetic flux density distribution having a plurality of peaks is generated, and when the plurality of peaks are represented as the first to m-th peaks Pm (m is an integer of 1 or more) in order from the side of the first connecting surface, a magnitude of the first peak P1 is larger than a magnitude of the third peak P3.
