The present invention relates to a biofoam comprising chitosan organic electrolyte, and more specifically, to a biofoam comprising chitosan organic electrolyte which enables the direct application of chitosan to the biofoam as a microcellular polymer foam comprising chitosan organic electrolyte and made of a polymer derived from a natural product and living organisms and improves adhesion to the human body while enabling a liquid material to be discharged in a sufficient amount for a long time when impregnating or applying a liquid material due to porosity, a sheet for the human body using the same, and a manufacturing method thereof. 본 발명은 키토산 유기전해질을 포함하는 바이오폼에 관한 것으로, 보다 상세하게는 키토산 유기전해질을 포함하고 천연물과 생체로부터 유래된 고분자로 만들어진 미세포상 고분자 발포체로서 키토산을 바이오 폼에 직접 적용시킬 수 있도록 하면서 다공성에 의하여 액상물질을 함침 또는 도포시에 액상물질이 충분한 양으로 오랫동안 배출될 수 있도록 하면서 인체부착성이 개선되도록 한 키토산 유기전해질을 포함하는 바이오폼 및 이를 이용한 인체용 시트 및 그 제조방법에 관한 것이다.
