Abstract
At the tip of a marginal land of a wiring board corresponding to a marginal electrode of a QFP is provided a partly projecting area that projects in a direction away from another land. The partly projecting area and the marginal land can be formed simultaneously and in a block by applying solder through a mask (not shown) on which openings are formed in the shape of the partly projecting area.
