Definitions

  • the heat transfer suppressing sheet 10 has excellent heat insulation performance, and that both the first inorganic fibers 23 and the second inorganic fibers 24 have low thermal conductivity.
  • the second inorganic fibers 24 preferably have a higher thermal conductivity than the first inorganic fibers 23 because they serve as heat transfer paths connecting the first inorganic fibers oriented in layers. Therefore, considering heat insulating performance, the thermal conductivity of the second inorganic fibers 24 is preferably 41 [W/m ⁇ K] or less.
