experiment example -
[0053] Hereinafter, an experimental example in which a reformed portion and a plating electrode were formed will be described.
[0054] (1) A sintered ceramic element body made of Ni-Cu-Zn-based ferrite is irradiated while scanning repeatedly with laser light. Although the processing conditions are as follows, the wavelength may be in any range from 532 nm to 10620 nm, for example. The irradiation interval refers to the distance between the forward path and the point center of the return path when scanning the laser light repeatedly.
