    摘要: Provided is a shower plate capable of more securely preventing the occurrence of backflow of plasma and enabling efficient plasma excitation. A shower plate 106 is disposed in a processing chamber 102 of a plasma processing apparatus and is provided with a plurality of gas discharge holes 113a for discharging a plasma excitation gas to generate plasma in the processing chamber 102, wherein an aspect ratio of a length of the gas discharge hole to a hole diameter thereof (length/hole diameter) is equal to or greater than about 20. The gas discharge holes 113a are made of ceramics members 113 which are separated from the shower plate 106, and the ceramics members 113 are installed in vertical holes 105 opened in the shower plate 106.
