The present invention provides: an electrode plate for secondary batteries, which has high reliability; and a secondary battery which uses this electrode plate. A negative electrode plate for secondary batteries, which comprises: a negative electrode core body that is formed of a metal; and negative electrode active material layers that are formed on both surfaces of the negative electrode core body. This negative electrode plate has a first edge and a negative electrode tab which protrudes from the first edge; and a coating film containing silicon is formed on the end face of the negative electrode core body at the first edge. A secondary battery according to the present invention is provided with a positive electrode plate and the negative electrode plate.
