<P>PROBLEM TO BE SOLVED: To provide a battery in which the detachment and dropout of a short circuit prevention layer and/or an active material layer is avoided during manufacturing and use of the battery. <P>SOLUTION: A battery includes a laminated electrode body in which a positive electrode 10, a negative electrode and a separator are laminated, and an alumina inclusion layer 40 including a γ-type alumina particle is formed in at least one member of the positive electrode 10, the negative electrode, and the separator. The alumina inclusion layer 40 includes the γ-type alumina particle, thereby obtaining high bond strength between the alumina inclusion layer 40 and an electrode made up of metals, a collector 11 constituting the electrode or an active material 12, or the separator. <P>COPYRIGHT: (C)2012,JPO&INPIT |
