Abstract

The present invention provides a method for producing a syringe gasket which is improved in liquid drug sealability by forming a minute projection on a circumferential surface of the gasket after demolding the gasket. In a method for producing a syringe gasket including a cylindrical main body (2) made of an elastic material and an inert resin film (3) laminated on a surface of the main body (2), at least one minute projection (5) is formed as extending circumferentially of the gasket on a surface of the inert resin film (3) laminated on the main body (2) by thermal processing using a laser beam.
