Abstract
An electromagnetic wave absorber (1a) includes a first layer (10) and an electrically conductive layer (20). The first layer (10) is a dielectric layer or a magnetic layer. The electrically conductive layer (20) is provided on at least one surface of the first layer. A product of a Young's modulus of the first layer (10) and a thickness of the first layer (10) is 0.1 to 1000 MPa·mm. The first layer (10) has a relative permittivity of 1 to 10.
