PART FOR PLASMA PROCESSING APPARATUS, MANUFACTURING METHOD THEREOF, AND PLASMA PROCESSING APPARATUS
A member for a plasma processing apparatus configured of a tubular body composed of a ceramic having a rare earth element oxide, aluminum oxide, or a rare earth element aluminum composite oxide as a main constituent and including a through hole in an axial direction, in which a number of recessed portions having a depth of from 10 μm to 20 μm, the depth starting from a ridge located between an inner peripheral surface of the tubular body and a target observation surface obtained by polishing from an outer peripheral surface of the tubular body toward an axis, is 2 or less per 1 mm of the ridge.
