PROBLEM TO BE SOLVED: To provide an inexpensive and efficient aligned multilayer-wound coil in which a small axial dimension can be set while maintaining a high conductor density, and an electric-magnetic energy transducer using the same. SOLUTION: The aligned multilayer-wound coil is formed by winding an insulated wire having an external diameter d in aligned multiplayer form, as shown in Fig. 1. In each stage of the coil, a coil-axial distance between two centers of adjacent wire portions is√3×d. One wire portion is overlapped and in close contact with another wire portion in a stage skipped by one wire portion perpendicularly to a coil axis, and two wire portions in adjacent stages are in close contact with each other having a level distance of d/2 in a zigzag manner. This causes wire portions 1 in columns to be in close contact with one another such that they are vertically stacked on one on another in each column, and they are axially stacked such that a wire portion 1 in an adjacent column is closely engaged in a trough formed by two wire portions 1 in vertical layers in each column. Thus, this configuration realizes a high wire density and a small axial dimension. Use of the aligned multilayer-wound coil realizes an electric-magnetic energy transducer having high performance.
