PURPOSE:To obtain a product of high quality both at a low price and with no flagging or protrusion without causing the necessity for incidental facilities, by providing a surface pressure supplementary layer to a required place on the surface of a gasket by the method of electrostatic printing. CONSTITUTION:A gasket main unit 1 is equipped with a water hole 4, oil hole 5, cylinder hole 6, grommet 7, etc. Here surface pressure supplementary layers 3, 3 are provided by the method of electrostatic printing to a surface pressure insufficient part on upper and bottom surfaces 2, 2 in the gasket main unit 1. Then a powdery material of, for instance, epoxy, acrylate resin and other synthetic resin or the like not containing at all an organic solvent or the like is used as a constitutional agent of the surface pressure supplementary layers 3, 3. In this way, a product of high quality both at a low price and with no flagging or protrusion can be obtained without causing the necessity for any incidental equipment. |
