An antenna device (1) includes: a winding component (2) having an approximately cylindrical shaped winding shaft portion (10) and a flange portion (12,13) disposed to project outside the winding shaft portion in at least one end portion of both end portions in an axial direction of the winding shaft portion; a pair of binding terminals (22) disposed to project outside the flange portion in at least one of the flange portions; and a winding (4) both ends of which are bound to the pair of binding terminals. The flange portion on which the binding terminals are disposed has an approximate disk shape. At least one binding terminal is disposed to be oriented along a direction approximately perpendicular to an outer periphery of the flange portion on which the binding terminal is disposed.

An out-of-plane micro-structure which can be used for on-chip integration of high-Q inductors and transformers places the magnetic field direction parallel to the substrate (14) plane without requiring high aspect ratio processing. The photolithographically patterned coil structure includes an elastic member (61 a) having an intrinsic stress profile. The intrinsic stress profile biases a free portion (11) away from the substrate (14) forming a loop winding (142). An anchor portion (12) remains fixed to the substrate (14). The free portion end becomes a second anchor portion (61 c) which may be connected to the substrate (14) via soldering or plating. A series of individual coil structures (140) can be joined via their anchor portions to form inductors and transformers.

Eine Spule (1) zur stehenden Montage auf Schaltungsträgern (2), wie z. B. auf Leiterplatten, wobei von dem oberen und dem unteren Ende der Spulenwicklung (1w) je ein Anschlußdraht (3, 6) im wesentlichen parallel zur Spulenachse (a) nach unten geführt ist, die Enden beider Anschlußdrähte über das untere Spulenende vorstehen, und der Anschlußdraht (6) für das obere Spulenende (lt) im Spuleninneren nach unten geführt ist. Dabei kann der Anschlußdraht (6) für das obere Spulenende (lt) im wesentlichen längs der Spulenachse (a) nach unten geführt sein, und die Spule kann einen rohrförmigen Spulenkörper (9) für die Spulenwicklung (1w) aufweisen.

In the winding wire at the winding completion end side, two wires are piled up vertically and wound together from the inner circumferential side towards the outer circumferential side. The winding wire at the winding start end side that has remained on the inner circumferential side is drawn forth from the inner circumferential side to the outer circumferential side so as to form a curve along the flat surface of the coil. In the crossing portions of the winding wire at the winding completion end side and the winding wire at the winding start end side, the two wires of each winding wire are superimposed and caused to cross each other in a state in which the wires are laid down transversely.
