Document Type and Number:
WIPO Patent Application WO/2020/196356
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a λ/4 type radiowave absorber capable of maintaining higher radiowave absorbability even in a use scene subject to condensation (preferably, a use scene in which droplets produced by condensation may be in liquid state). Provided is a λ/4 type radiowave absorber including a support body, a resistive film, a dielectric layer, and a reflective layer, wherein a contact angle on a surface on the opposite side to the resistive film side of the support body is more than or equal to 80 degrees.
