Zusammenfassung:	To provide an anode layer for all-solid battery of which the resistance is low.SOLUTION: The present invention relates to an anode layer used for an all-solid battery. The anode layer contains lithium titanate, a sulfide solid electrolyte and a rubber-based binder. In the anode layer, a ratio (A/B) of an adsorption amount A of the rubber-based binder adsorbed to the lithium titanate with respect to a total content B of the rubber-based binder contained in the anode layer is 1.35% or less.SELECTED DRAWING: Figure 5 【課題】本開示は、抵抗が低い全固体電池用負極層を提供することを主目的とする。【解決手段】本開示においては、全固体電池に用いられる負極層であって、上記負極層は、チタン酸リチウム、硫化物固体電解質、およびゴム系バインダーを含み、上記負極層に含まれる上記ゴム系バインダーの総含有量Ｂに対する、上記チタン酸リチウムに吸着している上記ゴム系バインダーの吸着量Ａの割合（Ａ／Ｂ）が、１．３５％以下である、負極層を提供することにより、上記課題を解決する。【選択図】図５
