According to one embodiment, provided is an electrode (3). The electrode (3) is provided with a current collector (3a), a first electrode cladding layer (3b_1) formed on the current collector (3a), and a second electrode cladding layer (3b_2) formed on the first electrode cladding layer (3b_1). The first electrode cladding layer (3b_1) includes a monoclinic crystal-type niobium-titanium complex oxide. The second electrode cladding layer (3b_2) includes a lithium titanium oxide with a spinel structure. Provided is the electrode, which can perform a nonaqueous electrolyte battery having excellent safety and lifespan properties. 하나의 실시 형태에 따르면, 전극(3)이 제공된다. 이 전극(3)은 집전체(3a)와, 집전체(3a) 상에 형성된 제1 전극 합재층(3b)과, 제1 전극 합재층(3b) 상에 형성된 제2 전극 합재층(3b)을 구비한다. 제1 전극 합재층(3b)은, 단사정형 니오븀티타늄 복합 산화물을 포함한다. 제2 전극 합재층(3b)은, 스피넬 구조의 티타늄산리튬을 포함한다.
