Abstract
An electromagnetic wave absorber (1a) includes: a first layer (10a) being a dielectric layer or a magnetic layer; and a conductive layer (20a) provided on at least one surface of the first layer (10a). The conductive layer (20a) has a sheet resistance of 100Ω/□ or less after the electromagnetic wave absorber (1a) is exposed to an environment having a temperature of 85° C. and a relative humidity of 85% for 1000 hours. The electromagnetic wave absorber (1a) has a flexural rigidity of 7000 MPa·mm4 or less.
