Abstract

A squeegee is slid over a metal mask plate so as to fill a sealing resin in a resin inflow space through a through hole, and the sealing resin, deposited on an outer surface of an electronic part that includes a vibrating part, is thermally set. A through hole that corresponds to an electronic part is formed in a metal mask plate. The through hole includes a lower smaller through hole and an upper larger through hole communicating with an upper side of the lower smaller through hole, and a step portion is formed within the through hole. A relief recess is provided in a region of a metal mask plate including at least a projected region in which an operating area is projected onto a surface of the metal mask plate opposing the touch panel in a state in which the metal mask plate covers the touch panel.
