Abstract

A secondary battery and an electronic device are provided. The secondary battery includes a first packaging portion and a second packaging portion, the first packaging portion including a first region and a second region connected to each other, and the second packaging portion including a third region and a fourth region connected to each other. The second region and the fourth region form a main body portion for accommodating an electrode assembly, and the first region and the third region are connected to form a sealing portion for sealing the main body portion, the sealing portion including a first sealing portion and a second sealing portion. A distance between a first metal plate and a second metal plate is less than 1.5 mm. A first insulating layer covers a surface of the first metal plate and is connected to the first region. A second insulating layer covers a surface of the second metal plate and is connected to the third region. Along a first direction, a sealing film is disposed between the first insulating layer and the second insulating layer. The sealing film includes a first surface facing the first region and a second surface facing the third region, where the first surface is bonded to the first insulating layer to form the first sealing portion, and the second surface is bonded to the second insulating layer to form the second sealing portion.
