Summary:PROBLEM TO BE SOLVED: To provide a thin battery capable of suppressing a deterioration of battery preservation property and a swell of the battery by using a current collecting terminal without burrs or warp to prevent a short circuit and an infiltration of moisture and oxygen into the battery. SOLUTION: In this thin battery, an electrode body being a power generating element is housed in a laminated exterior body 40. A strip-like current collecting terminal 20 electrically connected to the electrode body is projected from an opening of the laminated exterior body 40. The opening is sealed by welding. A corner 22 of the current collecting terminal 20 which corresponds to the welding region 49 of the laminated exterior body 40 is chamfered.
