IMPEDANCE MATCHING MEMBRANE FOR ELECTRIC WAVE ABSORBER, FILM PROVIDED WITH IMPEDANCE MATCHING MEMBRANE FOR ELECTRIC WAVE ABSORBER, ELECTRIC WAVE ABSORBER, AND LAMINATE FOR ELECTRIC WAVE ABSORBER

摘要

An impedance matching membrane 10 contains a metal element and a non-metal element. The impedance matching membrane 10 has a thickness of 10-200 nm. The impedance matching membrane 10 has a sheet resistance of 200 Ω/□ or more. In the impedance matching membrane 10, the contained percentage of oxygen atoms is not more than 50% in terms of the number of atoms.
