  "textContent": "There is provided a novel current collecting foil with conductive adhesive layer used for an anode-free battery. The current collecting foil with conductive adhesive layer includes a current collecting foil and a conductive adhesive layer, in which the conductive adhesive layer includes a matrix containing at least a polyisobutylene-based adhesive and a conductive material dispersed in the matrix, and contains 85 mass% or more and 95 mass% or less of the matrix and 5 mass% or more and 15 mass% or less of the conductive material with respect to the total mass of the conductive adhesive layer, the matrix contains the polyisobutylene-based adhesive, the polyisobutylene-based adhesive contains first polyisobutylene and second polyisobutylene, a weight average molecular weight of the first polyisobutylene is 30,000 or more and 200,000 or less, a weight average molecular weight of the second polyisobutylene is 500,000 or more and 5,000,000 or less, and 35 mass% or more and 85 mass% or less of the first polyisobutylene and 5 mass% or more and 60 mass% or less of the second polyisobutylene are contained with respect to the total mass of the conductive adhesive layer.",
