Abstract

A positive electrode material (216) is prevented from falling off from a current collector (212), and life characteristics are improved while suppressing hindering of movement of ions by a glass mat (300) and deterioration of capacity characteristics. A lead-acid battery (100) includes a positive electrode plate (210) including a current collector (212) and a positive electrode material (216) supported by the current collector (212), a negative electrode plate (220), a separator (230) disposed between the positive electrode plate (210) and the negative electrode plate (220), and a glass mat (300) containing glass fibers and disposed on the positive electrode material in the positive electrode plate (210). In this lead-acid battery (100), the glass fiber contained in the glass mat (300) includes a first glass fiber having a diameter of 8 m or more and 20 m or less and a second glass fiber having a diameter of 50 m or more and 100 pm or less, and a specific region where the positive electrode material, the first glass fiber, and the second glass fiber are mixed is present in at least one cross section substantially orthogonal to the positive electrode plate (210) in the positive electrode material and the glass mat (300).
