PROBLEM TO BE SOLVED: To provide a thin battery capable of maintaining performance by suppressing entering of moisture. SOLUTION: This is a thin battery 10 that has a terminal led out from the end edge of the outer periphery and is constructed of two sheets of positive electrode plates 101 onto which a positive electrode active material is applied, five sheets of separators 102 made of fine porous membrane, two sheets of negative electrode plates 103 coated with a negative electrode active material, a positive electrode terminal 104 connected to each positive electrode plate 101, a negative electrode terminal 105 connected to each negative electrode plate, an electrolyte not shown in the figure, battery outer packages 106, 107 sealing these, and a seal film 108 between the battery outer packages 106, 107 and the terminals 104, 105. The seal film 108 is constituted of a water-bridging resin and protrudes in nearly arc-shape from the outer peripheral edge of the battery outer packages 106, 107 to the lead-out direction of the terminal and covers a part of open cross-section of the battery outer packages 106, 107.
