The present invention relates to a plaster bandage and a plaster bandage manufacturing method capable of preventing side effects such as hypersensitivity reaction in a human body since the plaster bandage contains red clay which is good for human body and capable of smoothly molding the plaster bandage on an affected part since the viscosity of red clay dough is high. The plaster bandage is manufactured by mixing polyurethane resin, red clay powder, and algic acid, coating the mixture on a glass fiber, and turning the coated glass fiber into the plaster bandage. The manufacturing method comprises the following steps: grinding red clay (10S) filtering the ground red clay and extracting red clay powder (20S) mixing the extracted red clay powder, polyurethane resin, and algic acid (30S) and coating glass fiber with the mixed polyurethane resin, red clay powder, and algic acid and making a plaster bandage (40S). Since the plaster bandage is manufactured by mixing polyurethane resin, red clay powder, and algic acid and coating glass fiber with the mixture and turning it into the plaster bandage, the viscosity of the red clay dough is high when the plaster bandage is applied to a human body, so that the glass fiber is smoothly molded on a human body. Also, the plaster bandage does not cause side effects such as hypersensitivity reaction thanks to the contained red clay which is good for a human body.COPYRIGHT KIPO 2014[Reference numerals] (10S) Grind red clay (20S) Sieve ground red clay and extract red clay powder (30S) Mix the red clay powder, polyurethane resin, and algic acid (40S) Coat a glass fiber with the mixed polyurethane resin, red clay powder, and algic acid and complete a plaster bandage with the coated glass fiber (50S) Keep the completed glass fiber in a vacuum state in an airtight container such that the coated material does not get dry본 발명은 폴리우레탄 수지, 황토분말 및 알긴산을 혼합하여 유리섬유에 도포하고 그 도포된 유리섬유로 석고붕대를 구현함으로써 이 구현된 석고붕대를 인체에 적용 시 황토 반죽의 점성이 높아 해당 환부의 몰딩이 순조롭게 이루어
