Abstract
Between an anode active material layer and a separator, a recess impregnation region of an anode side in which electrolytes and solid particles are disposed and including a recess that is located between adjacent anode active material particles positioned on the outermost surface of the anode active material layer is formed. Between a cathode active material layer and a separator, a recess impregnation region of a cathode side in which electrolytes and solid particles are disposed and including a recess that is located between adjacent cathode active material particles positioned on the outermost surface of the cathode active material layer is formed. The solid particles in the recess impregnation regions of the cathode side and the anode side have a concentration that is 30 volume % or more.
