This application relates to the field of all-solid-state lithium battery technology, disclosing an adhesive composition, electrode sheet, and all-solid-state battery for all-solid-state batteries. The composition includes 0.5-5.0 parts of a modified polymer adhesive and 95.0-99.5 parts of a non-polar organic solvent. The modified polymer has a hydrocarbon backbone and side chains containing 0.5-15.0 mol% nitrile or ester groups. The electrode sheet of this invention contains only 0.5-3.0 wt% adhesive and is prepared using a high-pressure hot-pressing process at 300-1000 MPa, resulting in a point-contact distribution of the adhesive at the microscopic level.
