One embodiment of the present invention provides an electrode for a power storage element. The electrode has a conductive base material, an intermediate layer, and an active material layer provided inthat order. The intermediate layer includes a conductive agent, a polyolefin, and a binder. The content of the polyolefin is at least 2 times, but not more than 20 times the content of the conductiveagent in the intermediate layer, in terms of mass ratio. 本发明的一个方案是一种蓄电元件用的电极，其依次具备导电性基材、中间层和活性物质层，上述中间层包含导电剂、聚烯烃和粘结剂，上述中间层中的上述聚烯烃的含量相对于上述导电剂的含量以质量比计为2倍以上且20倍以下。
