PROBLEM TO BE SOLVED: To provide a sheet-like active material particle-containing molding which suppresses breakdown of secondary particles during manufacture of an electrode sheet and/or during rolling, when preparing a thick electrode, and to provide a secondary battery electrode, and a secondary battery using the same.SOLUTION: In this sheet-like active material particle-containing molding for the secondary battery, which contains not less than 80 weight % of active material secondary particles each having a volume average particle diameter of 1-100 μm, and the thickness of which is 0.3-3 mm, a binding material resin having tensile strength of not more than 300 kg/cm, and tensile elastic modulus of not more than 6.0×10kg/cmis contained between the active material secondary particles as a fibrous shape holding structure, the active material secondary particle contains an oxide active material primary particle having a volume average particle diameter of 0.1-1 μm, and the number average particle compression breakdown strength of the active material secondary particle is not less than 3 MPa.SELECTED DRAWING: Figure 1 |
