<p>In the plasma processing apparatus 10, a processing space S is formed between a susceptor 12 and an upper electrode 13 facing the susceptor 12. The plasma processing apparatus 10 includes a magnetic field generating unit provided at a side of the upper electrode 13 opposite to the processing space S. The magnetic field generating unit includes a magnetic force line generating unit 27 having a pair of annular magnet rows 27a and 27b. The annular magnet rows 27a and 27b are provided at the side of the upper electrode 13 opposite to the processing space S and arranged concentrically when viewed from the top. In the magnetic force line generating unit 27, an angleθ1 formed by axial lines of magnets of the annular magnet rows 27a and 27b is set to be in a range of about 0°<θ1≰180°.</p> |
