Matched-type electromagnetic wave absorber
A sheet-shaped matched-type electromagnetic wave absorber can obtain electromagnetic wave absorption performance with a relatively small thickness but has a problem that particularly a dimensional change in an electromagnetic wave absorption layer (resin composition layer) has a large influence on the electromagnetic wave absorption performance when being exposed to a high temperature. By laminating a resin composition layer in which a filler with an aspect ratio of 5 or more and a filler with an aspect ratio of less than 5 are dispersed and fixed with an electromagnetic wave reflection layer in a cured product of a resin composition containing an acrylic polymerizable resin and a polymerization initiator, it is possible to provide a matched-type electromagnetic wave absorber having high heat resistant dimensional stability and high electromagnetic wave absorption performance.
