The present invention relates to a method of manufacturing nutrition salt which has excellent emissivity of far-infrared rays and salt manufactured by the same. The method of manufacturing nutrition salt comprises the following steps: (a) preparing bay salt without brine； (b) filling 70% of a heat insulation container with the prepared bay salt, maintaining the temperature of the heat insulation container at 800-930°；C for 8-9 hours for completely melting the bay salt, and crushing the bay salt into a particle size of 2-3.4 cm； (c) filling 70% of the heat insulation container with the crushed salt, adding 0.02-0.1 parts by weight of germanium and tourmaline to 100 parts by weight of crushed salt, maintaining the temperature of the heat insulation container at 900-930°；C for 5-7 hours for completely melting the salt, crushing the salt into a particle size of 1-2 mm, and adding 0.01-0.03 parts by weight of yellow soil powder with a particle size of 2-10 um to 100 parts by weight of the salt powder； and (d) filling 80% of the heat insulation container with the salt powder, maintaining the temperature of the heat insulation container at 800-930°；C for 8-9 hours for completely melting the salt powder, and crushing the salt into a particle size of 0.3-1 mm. The nutrition salt emitting far infrared rays at room temperature is produced by adding minute contents of germanium and tourmaline, which are minerals emitting the far infrared rays. The nutrition salt is easy to be digested and absorbed by being crushed into a preferred particle size after melting the bay salt to form new salt crystals, and contains various natural components for producing the salt with high nutrition.본 발명은 원적외선 방사율이 우수한 영양 소금의 제조방법 및 그 소금에 관한 것으로, (a) 간수가 제거된 천일염을 준비하는 단계와； (b) 상기 준비된 천일염을 내열 용기의 70%까지 충전하여 800 내지 930℃의 온도로 8 내지 9시간 유지시켜 천일염이 완전 용융한 후, 입경 2 내지 3.4cm 크기로 파쇄하는 단계와； (c) 상기 분쇄된 소금을 내열 용기의 70%까지 충전하되, 상기 분쇄된 소금 100 중량부에 대하여 0.02 내지 0.1 중량부에 해당되는 게르마늄과 토르말린을 혼합하여 900 내지 930℃의 온도로
