Abstract

A laminate coil for an integral n-phase motor (n is a natural number of 2 or more) having pluralities of coil poles formed by patterned conductor coils formed in a laminate constituted by pluralities of insulating layers, the laminate coil comprising input and output terminals formed on an outer surface of the laminate, a first connecting line connecting the input terminal to the coil poles, and second connecting lines series-connecting coil poles having the same polarity, the first and second connecting lines being formed by conductor patterns, and the coil poles being formed on pluralities of insulating layers sandwiched by the first and second connecting lines.
