    • An object of the invention is to provide a current collector for a non-aqueous secondary battery in which the strength of the current collector is sufficient in forming an electrode plate and an active material can be efficiently disposed on the protrusions of the current collector, and to provide an electrode plate for a non-aqueous secondary battery and a non-aqueous secondary battery using the same. The invention relates to a current collector for a non-aqueous secondary battery, including a metal foil for carrying at least a positive electrode active material or negative electrode active material. Protrusions are formed in a predetermined arrangement pattern on at least one face of the metal foil and at least tops of the protrusions are not compressed. The arrangement pattern includes: a row direction in which the protrusions are aligned linearly at an equal pitch; and a column direction in which row units comprising a group of the protrusions aligned in the row direction are aligned in parallel at a predetermined interval. The respective protrusions of any one of the row units are displaced in the row direction from the protrusions of another row unit that is adjacent in the column direction. The invention also pertains to an electrode plate for a non-aqueous secondary battery and a non-aqueous secondary battery using the same.
