Via holes corresponding to the electronic parts are formed on the metal mask. The through hole includes a lower small through hole and an upper large through hole communicating with the upper side of the lower smaller through hole, and a step portion is formed in the through hole. An overflow recess is provided on the area of ​​the metal mask, and this area includes at least the state in which the metal mask covers the touch screen, and the operation area is projected onto the projection area on the surface of the metal mask opposite to the touch screen. Sovereignty Item 1. A vibration component resin sealing method of a touch screen input device, wherein the touch screen input device comprises an operation panel having an operation area, a touch screen supporting the operation panel, and a vibration component fixed to a part of the touch screen. The vibrating member corresponds to the periphery of the operation area, wherein an input operation is input to the operation area so that the operation panel is vibrated by the vibrating member to generate a feeling of an input operation, the method includes: setting includes The touch screen of the vibrating member is provided with a metal mask on a surface of the touch screen on which the vibrating member is mounted, the metal mask includes a through hole for accommodating the vibrating member, and the through hole is formed on the vibration A corresponding portion of the component is such that a resin inflow space is formed between the vibration component and the through hole; a squeegee is slid on the metal mask so that a sealing resin is filled in the resin inflow space through the through hole The sealing resin has thixotropic properties, thermosetting properties and insulating properties; the metal mask is removed from the touch screen; And the thermosetting resin is deposited on the outer surface of the vibrating member.
