The invention relates to a method of manufacturing a surface mounted (crystal) device comprising: the steps of providing an aggregated sheet material having a plurality of container main bodies lengthwise and crosswise, accommodating at least a crystal piece inside the concavities of the plurality of container main bodies formed in the aggregated sheet material, and then parting the aggregated sheet material into individual container main bodies. The method further includes: the steps of providing annular grooves on outer perimeters between the container main bodies of the aggregated sheet material; positioning an outer peripheral edge of an electrode roller having an inclined face of a seam welder inside the annular groove; abutting the inclined face against a metal cover tacked to the container main body; bonding the metal cover to an aperture end face of the container main body, by seam welding; and then parting the aggregated sheet material into individual container main bodies. The method also relates to an aggregated sheet material used for this method. As a result, positioning of the metal cover with respect to the container main body is simplified, the manufacturing processes are reduced, and a high productivity method of manufacturing surface mounted devices and an aggregated sheet material suitable for this are provided.
