Abstract: Provided is an internal pressure adjustment member to be attached to an outer surface of a housing, the member having high air permeability even when a differential pressure that can be generated between the inside and the outside of a housing to which the internal pressure adjustment member is attached is small, and inhibiting damage to the member and a reduction in the air permeability of the member due to coming soil and mud. The internal pressure adjustment member includes: a filter portion including a net-like or mesh-like support layer and first and second porous polytetrafluoroethylene (PTFE) membranes laminated on the support layer such that the support layer is interposed therebetween, the first porous PTFE membrane being exposed on one surface of the filter portion, the second porous PTFE membrane being exposed on another surface of the filter portion; and an adhesive portion, formed on the one surface of the filter portion, for attaching the filter portion to the outer surface of the housing. The first porous PTFE membrane and the second porous PTFE membrane each have an average pore diameter of 2.0 μm or more, the filter portion has a thickness of 140 μm or less, and the filter portion has a density of 0.60 g/cm3 or less.

Abstract: Provided is a plate-shaped composite material which can sufficiently exhibit an interference effect between antenna elements when utilized as, for example, a substrate of a microstrip patch antenna. The interference effect between the antenna elements can be sufficiently exhibited by controlling the composite material so that, when the material is divided into a plurality of regions, a standard deviation of density values of the respective regions is kept at a certain value or less.
