PROBLEM TO BE SOLVED: To improve impact resistance by securely holding an electrode provided in a case can with the remarkably simple structure. SOLUTION: This sealed battery is provided with the electrode body 1 arranged with a separator between a positive plate and a negative plate, the case can 2 for housing the electrode body 1, and a seal body 3 for sealing an opening part of the case can 2. The case can 2 is formed thick at a part opposite to the electrode body 1 to form a presser part 5 projecting from the inner surface of the case can 2, and this presser part pushes the outer peripheral surface of the electrode body 1.
