Holder, analysis apparatus including the same, and battery analysis method

An analysis apparatus for analyzing a battery, the analysis apparatus comprising:

• a holder that holds the battery;
• a spectrometer that disperses characteristic X-rays generated by irradiating the battery which is held by the holder with an excitation beam, and detects the intensity of each wavelength;
• and
• a signal processing device that processes a signal output from the spectrometer, wherein
• the battery includes a positive electrode and a negative electrode,
• the holder includes:
• a body with a sample chamber for disposing the battery therein and with a window in an incident direction of the excitation beam;
• a beryllium plate disposed in the window;
• a resin member provided on a surface of the beryllium plate;
• a conductive member provided between the positive electrode and the resin member so as to be in contact with the positive electrode of the battery;
• a positive electrode terminal electrically connected to the conductive member;
• and
• a negative electrode terminal electrically connected to the negative electrode.
