Coil substrate and motor coil substrate

A coil substrate, comprising:

• a flexible substrate having a first end and a second end on an opposite side with respect to the first end;
• and
• a plurality of coils formed on the flexible substrate in substantially one row between the first end and the second end of the flexible substrate such that each of the coils has a center space and a plurality of wirings surrounding the center space,
• wherein the plurality of wirings in each of the coils includes a plurality of parallel wirings formed substantially parallel to a row direction extending from the first end toward the second end and a plurality of perpendicular wirings formed substantially perpendicular to the row direction, and the plurality of coils is formed such that a thickness of the perpendicular wirings is greater than a thickness of the parallel wirings.
