    摘要： A method of producing a gasket in which burrs can be prevented from being formed, and a mold failure can be suppressed, and a gasket are provided. A method of producing a gasket includes: a step S1 of preparing a metal mesh member and expanded graphite; a step S2 of placing the metal mesh member around the expanded graphite in a manner that a long belt-like composite body in which the expanded graphite is enveloped by the metal mesh member is formed; a step S4 of adjusting the shapes of longitudinal end portions of the composite body in a manner that, in the short-side direction of the composite body, the width dimensions of the longitudinal end portions of the composite body are smaller than the width dimension of a longitudinal middle portion of the composite body; a step S5 of spirally winding the composite body in a manner that a tubular body in a multiply wound state in which an axial direction coincides with the short-side direction of the composite body is formed; and a step S6 of compress molding the tubular body in the axial direction of the tubular body.

    摘要： A gasket in which a high sealing property can be ensured, and a method of producing such a gasket are provided. A gasket 1 is produced by spirally winding a beltlike composite body 13 having a metal mesh member 11 and expanded graphite 12 enveloped by the metal mesh member, and then compression molding the composite body into a tubular shape. The gasket includes a first sealing portion 21 placed in one axial end portion, and a second sealing portion 22 placed in the other axial end portion. The gasket has a sectional shape in which the composite body that is in a bent state overlaps in a radial direction. The composite body includes a bent portion which is radially bent in an acute angle shape.
