NOVELTY - A packaging material comprises laminated component having sequentially arranged base material layer (1), bonding layer (2), metal layer (3) and sealant layer (4). The bonding layer has hardness of 20-115 MPa when indenter is pressed into bonding layer by 5 mu m from cross-section of laminated component using nano-indenter, peak temperature of 10-60 degrees C for loss modulus acquired when dynamic viscoelasticity is measured at frequency of 1 Hz, and ratio of integral value (IH) of peak areas in 2800-3000 cm-1, and an integral value (IM) of peak areas existing in 3100-3500 cm-1 is 0.15-1.5.    USE - Packaging material is used for manufacturing battery (all claimed) e.g. lithium-ion battery, lithium-ion polymer battery, lead storage battery, nickel-hydrogen storage battery, nickel-cadmium storage battery, ferronickel storage battery, nickel-zinc storage battery, silver oxide-zinc storage battery, metal air cell and polyvalent cation battery. Uses include but are not limited to electric vehicle, hybrid vehicle, personal computer, camera, mobile telephone, capacitor, and condenser.    ADVANTAGE - The packaging material has excellent moldability, versatility, and productivity, and prevents occurrence of crack and pinholes during molding.    DETAILED DESCRIPTION - A packaging material comprises laminated component having sequentially arranged base material layer, bonding layer, metal layer and sealant layer. The bonding layer has hardness of 20-115 MPa when an indenter is pressed into the bonding layer by 5 mu m from the cross-section of the laminate body using a nano-indenter, peak temperature of 10-60 degrees C for the loss modulus which is acquired when a dynamic viscoelasticity is measured at a frequency of 1 Hz for the bonding layer, and ratio of integral value (IH) of peak areas in 2800-3000 cm-1, and an integral value (IM) of peak areas existing in 3100-3500 cm-1 is 0.15-1.5, measured by using an infrared absorption spectrum. INDEPENDENT CLAIMS are included for the following:    (1) battery; and    (2) manufacture of battery.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of packaging material.
