A non-aqueous lithium-type power storage element that is formed by an electrode laminate body and a non-aqueous electrolyte being housed in an external body, the electrode laminate body having a negative electrode body, a positive electrode body, and a separator. The negative electrode body has a negative electrode power collection body and a negative electrode active material layer that includes a negative electrode active material and that is provided to one or both surfaces of the negative electrode power collection body. The negative electrode active material includes a carbon material that can occlude and release lithium ions. The positive electrode body has a positive electrode power collection body and a positive electrode active material layer that includes a positive electrode active material and that is provided to one or both surfaces of the positive electrode power collection body. The positive electrode active material includes activated carbon. The non-aqueous electrolyte contains, based on the total amount of the non-aqueous electrolyte, 0.5 mol/L or more of a lithium salt, and the negative electrode active material layer includes, per unit mass of the negative electrode active material, 2.6*10<-6>-2,000*10<-6> mol/g of a specific sulfur compound.
