A molar ratio (Co/Me) of Co contained in the Me ranges from 0.24 to 0.36, and when a space group R3-m is used for a crystal structure model based on an X-ray diffraction pattern, a half width of a diffraction peak that attributes to a (003) line ranges from 0.204° to 0.303°, or a half width of a diffraction peak that attributes to a (104) line ranges from 0.278° to 0.424°.",
