A laminated gasket (13) to be used for a medical syringe is provided, which includes a main body (14) made of an elastic material, and a film (15) provided on a surface of the main body (14). The gasket (13) has a circumferential surface portion (17) to be brought into contact with an inner peripheral surface (16) of a syringe barrel (11) of the syringe. The gasket (13) further includes a projection (22) provided on a surface portion of the film (15) present in the circumferential surface portion (17) as extending circumferentially of the gasket. The projection (22) has a height of not less than 15 µm and not greater than 55 µm and a width of not less than 30 µm and not greater than 75 µm. With this arrangement, the laminated gasket is excellent in sealability.
