NOVELTY - The electrode (100) has an active material layer (120) provided on a current collector (110). The active material layer contains an active material (121), a conductive agent (123) and a binder (125) and an acrylic based polymer i.e. copolymer. The active material layer contains polyvinylidene fluoride, where ratio of a total mass of the acrylic-based polymer to the sum of the total mass of the acrylic-based polymer and mass of the polyvinylidene fluoride is in the range from 40% by mass to 90% by mass. The conductive agent restrains the contact resistance with the current collector.    USE - Negative electrode for use in nonaqueous electrolyte battery i.e. flat type nonaqueous secondary battery, of battery pack (all claimed) for power sources for digital cameras or power sources on vehicles i.e. two- to four-wheel hybrid electric vehicles, two- to four-wheel electric vehicles and assist bicycles.    ADVANTAGE - The electrode has less weight, and allows improvement in the adhesive property between the current collector and the active material layer, so that the strength of the electrode can be improved to limit the occurrence of a phenomenon such as an electron conductive path being cut in the active material layer during charge/discharge of a battery. The electrode improves the current collecting performance of the active material layer when the amount of the conductive agent is 1% by mass or more, so that the content of the conductive agent is preferably 10% by mass or less to improve capacity. The electrode formulates conductive agent to improve current collecting performance such as large capacity and long life, and restrains the contact resistance with the current collector.    DETAILED DESCRIPTION - The active material selected from the group consisting of lithium titanate with spinel structure, a monoclinic beta-type titanium complex oxide, silicon, silicon-containing complex oxide, and graphite.
