Abstract

A welding method includes pressing multiple objects together by a jig and irradiating the objects with laser to form multiple welded spots. The welded spots may include multiple first welded spots formed in a first direction and multiple second welded spots formed in the first direction and misaligned with the first welded spots in a second direction which is perpendicular to the first direction. A gap between the center of each of the first welded spots and the center of each of the second welded spots in the second direction. Another gap between the first welded spots in the first direction. And a gap between the second welded spots in the first direction may be greater than or equal to the radius of the second welded spot and less than or equal to a value of about 1 mm plus a diameter of the second welded spot.
