There is provided a multilayer coil component in which the stress concentration at an overlapped area, such as the area between a pad area and a via-hole conductor, is mitigated to obtain preferable characteristics and troubles such as a short-circuit failure and a mounting failure are eliminated. A method for fabricating the multilayer coil is also provided. In the multilayer coil component, ceramic layers (1) and coil conductors (11) are stacked each other and pad areas (12) formed at the end of the coil conductors (11) are interlayer-connected through via-hole conductors (13) to form a spiral coil. The thickness of the pad areas (12) is formed thinner than that of the coil conductors (11), thereby mitigating the concentration of the stress at the overlapped areas between the pad areas (12) and the via-hole conductors (13).

A coil component includes coil windings, and resin portions that are insulating members having electrical insulation properties and integrally formed with the coil windings covering parts of surfaces of the coil windings, and the coil component is sandwiched by magnetic core members in directions of winding axes of the coil windings. The coil windings are composed of a plurality of plate-like coil members in a ring shape having ends joined in a stacking direction with a clearance therebetween to be continuous in a predetermined winding direction. The resin portions that are the insulating members cover outermost plate surfaces of the coil members facing the magnetic core members, a space between the adjacent coil members, and inner perimeter edges of the coil members, and have openings along the directions of winding axes of the coil windings.

The invention relates to a stator for an electric motor comprising several poles (P) that are directed inwards towards the motor axis (2) and that surround a rotor (1), each pole (P) being provided with one winding (L) and the coils of the windings (L) being wound around the poles (P) one after the other without interruption. The stator (20) contains at least three pole groups (n), having at least three poles (P) and each group having the same number of poles (P). The windings (L) run out from the end face at least at the respective beginning and end of a pole group and are contacted there in such a way that the windings (L) associated with each pole group contain their own connection pair (U-U', V-V', W-W') and one connection (U', V', W') of each of these connection pairs is connected to a star point (Y) on the end face of the stator (20). The windings (L) are wound around the poles (P) one after the other with an alternating winding direction (WR), a single pole (P) having a winding (L) with the same winding direction as the preceding winding (L) of the preceding pole group (n) at an individual transition point between two pole groups (n).
