<p>A resin molded coil is configured by providing multiple layers of a prepreg layer (41,42,43,44) and a fiber glass-base layer (31,32,33,34) in the inner/outer circumference resin layers in the radial direction of the concentric circle of a coil (1) and a winding wire to make the resin layer multiply-layered and subdivided. This configuration reduces the resin contraction amount of each layer and increases crack resistance.</p> |
