BATTERY PACK AND LIGHTING DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a battery pack with improved assembly workability, and to provide a lighting device using the battery pack.SOLUTION: A battery pack 10 includes: a unit cell 2A; a connection member 1; and a heat-shrinkable member 3. The connection member 1 has a connection terminal electrically connected with the unit cell 2A and is electrically and mechanically connected with an external device. The heat-shrinkable member 3 covers the unit cell 2A and the connection member 1 while exposing at least a part of the unit cell 2A and the connection member 1 and is shrunk by heat thereby integrally holding the unit cell 2A and the connection member 1.
