Abstract: A secondary battery includes a battery case housing a flat electrode body and a sealing plate. The electrode body is housed in the battery case such that a winding axis thereof is parallel with a longitudinal direction of the sealing plate. At an end portion of the electrode body in a winding axis direction thereof, an edge of a positive or negative electrode plate is connected to an external terminal fixed to the sealing plate through a current collector. An insulating pressing member is arranged between the sealing plate and the electrode body. The pressing member presses the electrode body in a direction perpendicular to the winding axis such that a distance between a portion of the electrode body contacting the pressing member and the sealing plate is longer than a distance between the end portion of the electrode body in the winding axis direction thereof and the sealing plate.
