FREQUENCY SELECTING PLATE

PURPOSE:To make good adhesion to a conductive member to a substrate and to decrease the transmission loss of an electromagnetic wave by making the substrate out of a specific composite material and making adhesives for bonding a honeycomb core to the substrates adhere by avoiding a substrate part facing the core center part of the honeycomb core. CONSTITUTION:Substrates 31 and 32 are made of the composite material of at least aramide fiber and polyamide resin whose water absorption is 0.2% or below and tandelta is 0.02 or below and adhesives 21 and 22 for bonding a honeycomb core 1 and the substrates 31 and 32 together are made to adhere by avoiding the substrate part facing the core center part of the honeycomb core 1. Thus, the swelling of the substrates by washing and drying becomes small, the adhesion of the substrate 31 to a conductive member 4 becomes good, the transmission loss of the electromagnetic wave becomes little and it becomes the one fit for a space navigation body.
