PROBLEM TO BE SOLVED: To provide a magnetic kinetic mass part for a mobile telecommunication equipment which improves the adhesiveness between a holder of a zinc die casting and rare earth magnets, also improves moisture resistance, suppresses the deterioration of the adhesiveness particularly after storage at low temperatures and is excellent in reliability. SOLUTION: The magnetic kinetic mass part has rare earth magnets 10A, 10B bonded to a holder 1 obtained by successively forming a Cu plating layer as an underlayer and a plating layer of one or more selected from Ni and Ni-P, Ni-B and Ni-Sn alloys on a zinc die casting. The rare earth magnets 10A, 10B are Nd-Fe-B magnets each with a plating layer of Ni or an Ni-P, Ni-B or Ni-Sn alloy formed on the top. |
