Disclosed is a particulate matter (PM) capturing and collecting filter device having a target-coated liquid film. More specifically, disclosed is a PM particle capturing and collecting filter device having a target-coated liquid film in which a spreading phenomenon in which a liquid material spreads outside the filter is suppressed. Disclosed is a filter device for capturing and collecting PM particles, in which a liquid film having interface energy control and capillary force induction is used for effective PM particle capturing and collecting, and a surrounding portion is formed for preventing spreading of a liquid material on a substrate.
