PROBLEM TO BE SOLVED: To provide a battery that uses a reed terminal having a large cross section corresponding to a large current charge and discharge and is superior in sealing reliability in the sealing part of the reed terminal, and a method of manufacturing stably the battery having superior sealing reliability in the reed terminal sealing part. SOLUTION: At least one of the positive electrode reed terminal and the negative electrode reed terminal is made a flat metal reed 3 having a cross section of 3 mm<SP>2</SP>or more. The ratio of width/thickness of the flat metal reed 3 is made 200 or more, and a heat resistant resin layer 4a is provided between an inner resin layer 1a and the flat metal reed 3 at the drawing-out sealing side of the flat metal reed 3. With respect to the thickness of the inner resin layer 1a at the drawing-out sealing side of the flat metal reed 3, the thickness A1 of the inner resin layer 1a at the reed terminal sealing part 6 is made thinner than the thickness A2 of the inner resin layer at the joint 7 where the inner resin layers 1a are thermally fused to each other.
