Anode of secondary cell, the manufacturing method of anode of secondary cell and all solid state secondary battery

Provide the high anode of secondary cell of capacity maintenance rate, anode of secondary cell manufacturing method and have all solid state secondary battery of the anode.The above subject is solved by providing the anode of secondary cell characterized by as follows, the anode of secondary cell has the positive electrode active material layer including at least positive active material and solid electrolyte: the oil absorption of the positive active material is 35~50ml/100g, the average grain diameter of the solid electrolyte is 1.5~2.5 μm, and the positive electrode active material layer is made of the positive active material and the solid electrolyte are mixed, are press-formed to the mixture under solvent-free.
