Claims7
A pressure sensitive adhesive sheet for batteries, comprising:
- a base material layer and a pressure sensitive adhesive layer provided on only one surface side of the base material,
- the pressure sensitive adhesive layer contains inorganic fine particles,
- the inorganic fine particles comprise at least one of calcium carbonate and aluminum hydroxide, and are free from alumina,
- an average particle diameter of the inorganic fine particles is 0.8 μm or more and 10 μm or less,
- a haze value of the pressure sensitive adhesive layer is 50% or more and 85% or less, and
- a thickness of the pressure sensitive adhesive layer is 1 μm or more and 10 μm or less.
