An impedance matching film 10a has a plurality of openings 11. The plurality of openings 11 are formed at equal intervals in a specific direction along main surfaces 10f of the impedance matching film 10a. The impedance matching film 10a has a sheet resistance of 300 to 700Ω/□. A size G of each opening 11 in the specific direction is 50 μm or more and 1000 μm or less.
