摘要：
Described is a pressure relief mechanism, a battery cell, a battery, an electric apparatus, and a manufacturing method thereof. A pressure relief mechanism is provided on a housing plate of a battery cell and includes: a connecting portion, where the connecting portion is located at an outer peripheral region of the pressure relief mechanism and is configured to connect the housing plate; a first part, where an end of the first part is connected to the connecting portion, and another end protrudes obliquely toward an interior of the battery cell; a weak portion, where the weak portion is provided at the protruding end of the first part; and a second part, where an outer edge region of the second part is connected to the weak portion, and the outer edge region extends obliquely away from the interior of the battery cell.
