Zusammenfassung:	Provided are an electrode for a secondary battery and a manufacturing method thereof. According to the present invention, a secondary battery, which has high capacity and is also able to get an excellent evaluation in a nail penetration test so that stability is ensured, may be manufactured. In order to accomplish the above objectives, the present invention provides an electrode for a secondary battery which includes an electrode current collector; a first electrode active material layer formed on the electrode current collector; and a second electrode active material layer formed on the first electrode active material layer, wherein a layer composed of the electrode current collector and the first electrode active material layer has a tensile strain of 1.2% or less.
