A condenser of a condensing-type dryer is provided. In the condensing-type
dryer, a hydrophilic film is formed on a heat emission plate by a plasma
discharge. In the heat emission plate, an indoor air can be heat
exchanged with a circulation air cycling in a drum. A contact angle of a
condensed waterdrop formed on the heat emission plate is decreased
through the hydrophilic film, thereby making it possible to decrease a
flow resistance due to the condensed waterdrop.
