At least, a base layer, an adhesive layer, a barrier layer, and a heat-fusible resin layer, which is composed of a laminate including in this order, In the thermomechanical analysis for measuring the displacement of the probe, the probe is set on the surface of the adhesive layer in the cross section of the laminate, and the set value of the deflection of the probe at the start of the measurement is -4 V, and the temperature rise rate is 5 A packaging material for a battery, wherein a temperature at which the displacement of the probe is maximum when the probe is heated from 40 ° C. to 350 ° C. under a condition of ° C./min is 190 ° C. or more and 320 ° C. or less. |
