Document Type and Number:
WIPO Patent Application WO/2023/210720
Kind Code:
A1
Abstract:
A filter structure (81) is adhered to an object so that a gas passing therethrough is filtered and comprises: a filter layer that is formed from a member that is in a sheet form and has gas permeability; and an adhesive layer that is formed on at least a part of a surface of the filter layer on one side and is adhered to the object. The adhesive layer includes at least 3% by weight of a flame retardant. With this configuration, flame retardancy is imparted to the adhesive layer, and thus the flame retardancy of the filter structure (81) as a whole can be increased.
