摘要:
An impedance matching film 10 includes a metallic element and a non-metallic element. The impedance matching film 10 has a thickness of 10 to 200 nm. The impedance matching film 10 has a sheet resistance of 200 Ω/□ or more. In the impedance matching film 10, the content of an oxygen atom is less than 50% in terms of the number of atoms.
