Claim 2:
3. An insole coupled with a sheet-type coated cork, comprising:
the sheet-type coated cork manufactured so as to have a sheet shape having a thickness of 0.2 to 4 mm by slicing a block-type coated cork in which crushed cork pieces having a diameter of 5 to 10 mm are coupled with each other and a plurality of main-body-coupling openings, which are empty spaces, are formed between the crushed cork pieces using a latex for coating obtained by performing curing; and
a main body of the insole laminated on a lower portion of the sheet-type coated cork,
wherein a space occupancy ratio of the plurality of main-body-coupling openings is 10 to 60% based on an apparent volume of the block-type coated cork, an apparent specific gravity of the block-type coated cork is 0.12 to 0.35 g/cm3, and a part of the main body of the insole is inserted into the main-body-coupling openings in the sheet-type coated cork and is exposed through the main-body-coupling openings to an outside by pressing and heating to be coupled each other.
