Abstract:
1. A nonaqueous electrolyte battery pack comprising a nonaqueous electrolyte battery cell, a circuit board, a nonaqueous electrolyte-absorbing element for absorbing a nonaqueous electrolyte solution in the event of electrolyte leakage from the nonaqueous electrolyte battery cell, and a battery case encasing the battery cell, the circuit board and the nonaqueous electrolyte-absorbing element, wherein the nonaqueous electrolyte-absorbing element is formed of a liquid absorbing sheet for absorbing a nonaqueous electrolyte solution, comprising: a liquid-absorbing resin layer capable of absorbing a nonaqueous electrolyte solution and shows adhesion, wherein the liquid-absorbing resin layer comprises a polymer of a monomer composition, the monomer composition containing: a monofunctional monomer component (A) comprising a polyethylene glycol acrylate monomer and an amide bond-containing acrylic monomer; and a polyfunctional monomer component (B).
