  "textContent": "Provided is art that allows joining an external conductive member and a bus bar more stably. A method for producing a secondary battery (1) disclosed herein has: an attachment step; an arrangement step; a covering step; and, a joining step. The external conductive member (35) has a recess (35a) sunk from the upper surface (35u), around a through-hole (35h). In the joining step, the external conductive member (35) and the terminal (30) are joined in a state where an edge portion of a cover member (2) is disposed between a planned joint portion (31w), and an outer peripheral edge of the recess (35a), in a cross-sectional view along a direction of penetration into the through-hole (35h).",
