PROBLEM TO BE SOLVED: To provide a light-weight and highly durable finger pressure implement using a germanium chip which is hardly damaged by impacts during use and enables the cost thereof to be suppressed more than before though using pure germanium. SOLUTION: The finger pressure implement using the germanium chip has such constitution that a case is made of titanium, an opening part is provided on one surface of the case 21, the germanium chip 15 having a projected end 11 projected from the opening part 25 to the outside of the case and a base part 12 arranged inside the titanium-made case is housed inside the titanium-made case together with a magnet piece 27, and an opening part 25 on the other surface of the titanium-made case 21 is closed by a titanium-made lid body.
