  "textContent": "Embodiments of this application provide a pressure relief mechanism, a battery cell, a battery, an electrical device, and a pressure relief mechanism manufacturing method. The pressure relief mechanism is disposed on a housing plate of a battery cell, and including: a connecting portion, located in a peripheral region of the pressure relief mechanism, and configured to connect to the housing plate; a first part, where one end of the first part is connected to the connecting portion, and the other end of the first part extends out obliquely toward an interior of the battery cell; a fragile portion, connected to the extending end of the first part; and a second part, taking a shape that protrudes toward the interior of the battery cell, where an outer edge region of the second part is connected to the fragile portion. When an internal temperature or gas pressure of the battery cell is less than a first preset value, the fragile portion is squeezed and pressed by the first part and/or the second part. The technical solutions of embodiments of this application can effectively extend the lifespan of the pressure relief mechanism.",
