ABSTRACT:
This invention provides a germanium-containing health promoting appliance which is used by making it into contact with the skin, which is produced at low cost without requiring the after-machining. The health promoting appliance is made of a sintered material composed of 2 to 20% by mass of germanium and the remainder of stainless steel, the fine pores of which are desirably sealed up by a resinous material and it is produced by sintering a green compact of desired shape of powder mixture of the above composition, under the rate of temperature rise of 10° C. per minute or less from 800° C. to the retaining temperatures of sintering at 1000 to 1300° C.
