PROBLEM TO BE SOLVED: To provide a method for manufacturing a seal product, capable of surely preventing adhesion prevention between plate-like members in a manufacturing process, and free from the needs of forming an escape hole for storing an adhesion prevention projection on a mating surface to mount the seal product on.SOLUTION: A method for manufacturing a seal product includes molding by a molding die a seal member made of a rubber-like elastic material on a plate-like member made of a metallic material and provided with an adhesion prevention projection. The plate-like member provided with the adhesion prevention projection is prepared on the circumference of a notch part formed on part of the circumference of the plate-like member, and the adhesion prevention projection is crushed by the molding die when molding the seal member made of a rubber-like elastic material by the molding die on the plate-like member, and part of the crushed adhesion prevention projection extends to the notch part so as to make a state where the adhesion prevention projection is not projected from the surface of the plate-like member. 【課題】製造工程において、板状部材相互の粘着防止を確実に防止できると共に、シール製品を取り付ける相手面に貼り付き防止突起を収容する為の逃がし穴を形成する必要が無いシール製品の製造方法を提供することを目的とするものである。【解決手段】貼り付き防止突起を設けた金属材製の板状部材にゴム状弾性材製のシール部材を成形金型により成形するシール製品の製造方法において、前記板状部材の周縁の一部に形成した切り欠き部の周縁に前記貼り付き防止突起を設けた前記板状部材を準備し、ついで前記板状部材にゴム状弾性材製の前記シール部材を前記成形金型により成形する際に、前記貼り付き防止突起が前記成形金型により押し潰されると共に、この押し潰された前記貼り付き防止突起の一部が前記切り欠き部に張り出す事により、前記貼り付き防止突起が前記板状部材の表面から突出しない状態を作り出すことを特徴とする。【選択図】図２
