PROBLEM TO BE SOLVED: To provide a packing method using a tray and its lid whose base material is thermoplastic resin, on both sides thereof a layer of conductive polymer is coating-formed, for packing a magnetic circuit for a voice coil motor of a hard disk drive. SOLUTION: The packing method uses the tray and its lid whose basic material is thermoplastic resin, on both sides thereof the layer of conductive polymer is coating-formed, for packing the magnetic circuit for the voice coil motor of the hard disk drive to which the final cleaning is carried out. Consequently, it is possible to provide a magnetic circuit for the voice coil motor of the hard disk in which the number of particles larger than or equal to 1.0μm is further reduced and the number of microparticles (micro foreign particles) smaller than 1.0μm is small when taking out a product from the package.
