본 발명은, 제조 시나 사용 시에 단락(短絡) 방지 및 그 외의 기능을 가지는 층 및/또는 활물질층이 쉽게 박리·탈락되지 않는 축전 소자용 전극 및 축전 소자를 제공한다. 집전체박(集電體箔)(11)과, 집전체박(11) 중 적어도 한쪽의 표면 상에 형성된 활물질층(12)과, 집전체박(11)의 표면 상에 형성되고, 활물질층(12)과 인접하는 고저항층(40)을 가지고, 활물질층(12)과 고저항층(40)과의 계면(50) 중 적어도 일부에는, 2개 층(12, 40)의 조성(組成)을 포함하는 혼합상(混合相)(51)이 형성되어 있는 축전 소자용 전극(10). 활물질층(12)과 고저항층(40)의 계면(50)이 혼합상(51)을 가지는 것에 의해, 인접하는 2개 층(12, 40)의 접합이 견고하게 된다.

    PROBLEM: To provide an electricity-storing device and an electrode for an electricity-storing device which, during manufacture and use, have less tendency to experience delamination or loss at active material layer(s) and/or layer(s) provided for short circuit prevention or serving other function(s). SOLUTION MEANS: Electricity-storing device electrode 10 comprises current collector foil 11; active material layer 12 formed on at least one surface of current collector foil 11; and high-resistance layer 40 formed on surface(s) of current collector foil 11 so as to be adjacent to and in direct contact with active material layer 12; wherein, at at least a portion of interface 50 between active material layer 12 and high-resistance layer 40, mixed phase 51 is formed where constituents from the two layers 12, 40 intermingle. By causing mixed phase 51 to be present at interface 50 between active material layer 12 and high-resistance layer 40, the bond between the two adjacent layers 12, 40 is made strong.
