Abstract
Provided are: a filter medium with high dust collection efficiency, low pressure loss, and a long lifespan; and a filter material used for the filter medium. This composite structure includes ultrafine fibers having a fiber diameter of less than 500 nm, and beads. The outermost surface of the composite structure has at least 500/mm2 of beads with a diameter of 5 μm or more. The ultrafine fibers and the beads preferably have the same component.
