PURPOSE: To manufacture a sheet having a chain wherein conductive particles are nearly uniformly and spacedly placed, by mixing many conductive ferromagnetic balls in unhardened and unconductive polymer. CONSTITUTION: Many conductive ferromagnetic balls 16 are mixed previously in unhardened and unconductive polymer 12. Next, the polymer 12 is spread in a sheet 10, and the sheet 10 is hardened in a magnetic field, having alternate regions wherein regions having high and low magnetic field strength are neary uniformly and spacedly placed, and changing in space. When balls 16 mixed in the polymer sheet 10 are collected in the regions 22 and 24 having high magnetic field strength respective, the respective balls 16 form one or more chains 14, wherein the chains 14 are parallel to a magnetic line of force, and are aligned in range with each other, thereby placing the chains 14 in nearly uniformly and spacedly. The laterally directional interval between the chains 14 can be sufficiently controllable by adjusting a laterally directional interval between the regions 22 and 24. |
