Abstract
A filter structure (81) is used for filtering a gas passing therethrough by being attached to an object, and includes a filter layer made of a sheet-like member having air permeability, and an adhesive layer formed on at least a part of one surface of the filter layer and configured to attach to the object. The adhesive layer contains 3 wt % or more of a flame retardant. With such a configuration, flame retardance is imparted to the adhesive layer, and thus it is possible to improve flame retardance of the entire filter structure (81).
