Summary:PURPOSE:To reduce an increase of an electric resistance by a skin effect, prevent a lowering of a voltage in a high frequency and improve a deterioration in a sound quality by using a magnet wire made of a stranded wire in a power generating coil of a pick up cartridge. CONSTITUTION:A magnet wire 8 is a stranded wire in which three single lines are stranded and on a surface thereof, an insulating coating or an insulating layer for an electrical insulation is disposed. A current capacity flowing through a single stranded line goes to 3/1, a radius r2 of the single stranded line is small and a skin effect becomes small to make a distribution of the current capacity substantially fixed and an increase of an electric resistance an by alternating current is remarkably improved.
