PROBLEM TO BE SOLVED: To supply an electrolyte into a battery can with an opening of the battery can sealed by a lid material, in a sealed secondary battery composed by storing, in the battery can, an electrode body with a separator interlaid between a positive electrode and a negative electrode and the electrolyte, and by sealing the opening of the battery can by a lid material with a terminal cap mounted thereto. SOLUTION: This sealed secondary battery is so structured that the electrode body 10 with the separator 3 interlaid between the positive electrode 1 and the negative electrode 2, and the electrolyte 41 are stored in the battery can 20; and the opening of the battery can is sealed by the lid material 30 with the terminal cap 31 mounted thereto. A through-hole 30a is formed in a part of the lid material covered with the terminal cap; an electrolyte-injecting hole 31b is formed in the terminal cap; a sealing member formed of an airtight elastic body is stored in a space part between the terminal cap and the lid material; and the through-hole and the electrolyte-injecting hole are sealed by the sealing member.
