## Abstract

A heat insulation sheet and a sheet material using the heat insulation sheet. The heat insulation sheet is provided with a fixing layer that is arranged between a base material and a carbon sheet. The fixing layer is made of a pressure-sensitive adhesive. The base material has flexibility. The carbon sheet is made by rolling expanded graphite and has a thickness from twenty-five micrometers to one hundred micrometers. In the sheet material, activated carbon is arranged opposite to the fixing layer side of the heat insulation sheet, and a surface material is arranged on a surface of the activated carbon. The fixing layer can be constituted in such a manner that a hot-melt adhesive is arranged in a reticulate manner.

## Claims

### Claim 1

A heat insulation sheet for use in an interior material for a wall, a ceiling, a curtain, and a blind, the heat insulation sheet comprising:
a base material made of paper or fabric and having flexibility;
a carbon sheet made by rolling expanded graphite and having a thickness from twenty-five micrometers to one hundred micrometers;
a fixing layer being arranged between the base material and the carbon sheet, the fixing layer being made of an acrylic solvent-based hot-melt pressure-sensitive adhesive or a silicon-based hot-melt pressure-sensitive adhesive,
an activated carbon layer arranged outside of the carbon sheet on an opposite face to the fixing layer, the activated carbon layer housing a functional substance, and
a surface material with good ventilation property attached to an outer face of the carbon sheet,
wherein the surface material is a paper sheet, a fabric sheet, a textile fabric sheet, a vinyl chloride sheet, or a natural leather.

### Claim 2 (depends on 1)

The heat insulation sheet for use in an interior material for a wall, a ceiling, a curtain, and a blind according to claim 1,
wherein the functional material is at least one of deodorizing-decomposing enzyme, antibacterial agent, and perfuming agent.
