The present invention relates to a functional patch for a pad, which is useful for the human body. The functional patch is manufactured via: a ferrite mixing process (S110) of mixing 45-55 wt% of ferric oxide, 12-16 wt% of nickel oxide, 14-18 wt% of zinc oxide, 4-6 wt% of copper oxide, 4-8 wt% of lithium, 4-8 wt% of barium, and 2-4 wt% of magnesium to compose a ferrite mixed material； a ferrite material suspending process (S120) of putting 130-170 wt% of water, 2-4 wt% of a dispersing agent and 2-3 wt% of a binding agent with respect to the weight of the mixed material to make the mixed material into a mixture in a suspension state； a ferrite material granulating process (S130) of spraying and drying the mixture in a suspension state to make the mixture into a granular ferrite material； a heating and sintering process (S140) of heating the granular ferrite material at a temperature of 1,000-1,400°；C for 3-8 hours to form a sintered ferrite material； a sintered ferrite material pulverizing process (S150) of pulverizing the heated and sintered ferrite material into powder； a sintered ferrite material liquefying process (S160) of mixing 40-60 wt% of the sintered ferrite material powder and 40-60 wt% of water, putting 2-6 wt% of a natural mordant with respect to the weight of a mixture composed of the ferrite powder and the water, and aging the mixture for 12-24 hours； and a printing process (S170) of printing the liquefied and sintered ferrite material on fabric in a certain design and pattern.본 발명은 인체에 유익한 패드용 기능성 패치이다. 그 구체적인 구성은 다음과 같다. 산화제2철 45~55중량%, 산화니켈 12~16중량%, 산화아연 14~18중량%, 산화구리 4~6중량%, 리튬 4~8중량%, 바륨 4~8중량% 및 마그네슘 2~4중량%를 혼합하여 페라이트 혼합원료를 조성하는 페라이트 배합공정(S110)과； 상기 혼합원료의 무게에 대하여 물 130~170중량%, 분산제는 혼합원료의 무게에 대하여 2~4중량%, 결착제는 혼합원료의 무게에 대하여 2~3중량%를 투입하여 현탁액(懸濁液)상태의 혼합물로 만드는 페라이트원료의 현탁화 공정(S120)과； 상기 현탁액(懸濁液) 상태의 혼합물을 분무 건조하여 과립상으로 만드는 페라이트원료 과립화 공정(S130)과； 과립상의 페라이트원료를 3~8시간 동안 1,000~1,400℃ 온도로 가열하여 페라이트소결체(Ferrite燒結體)를 소성하는 열처리 소결공정(S140)과； 상기 열처리된 페라이트소결체를 분
