Abstract

Measurement can be performed even when spaces divided by a partition film have a pressure difference therebetween, and the partition film is easily extended without causing warping and wrinkles. Provided is an X-ray fluorescence spectrometer, which includes: an irradiation chamber, an inside of which is vacuum; and a sample chamber, an inside of which has an atmospheric pressure, the X-ray fluorescence spectrometer including: a window frame holding member, which forms a part of a partition wall between the irradiation chamber and the sample chamber, and includes an opening for allowing the X-rays to pass therethrough; and a window frame member, which is configured to hold a partition film, and is to be arranged in the opening of the window frame holding member, the partition film being formed from a material that transmits the X-rays, and being a part of the partition wall. The window frame member includes: an inner film holding member having an annular shape, the inner film holding member including a peripheral wall extending from a proximal end to be arranged on the sample chamber side toward a distal end to be arranged on the irradiation chamber side, the distal end having an opening to be closed by a part of the partition film; and an outer film holding member having an annular shape, the outer film holding member being configured to be inserted from the distal end of the inner film holding member to be mounted to the proximal end of the inner film holding member so as to fix a surrounding of the part of the partition film to the inner film holding member.
