Embodiment Construction

[0086] FIG. 1A shows an embodiment of an inductive element according to the invention in a perspective view. FIG. 1B shows the structure of a coil in the inductor coil in a cross-sectional view. FIG. 1C shows the structure of an electrode in the inductor element in a cross-sectional view. FIG. 2A shows the inductance element in a bottom view. Figure 2B The inductance element is shown in a cross-sectional view.

[0087] In FIGS. 1A-1C and FIGS. 2A and 2B, reference numeral 1 denotes a rectangular spiral coil. The coil 1 includes a pair of parallel conductive members 2a and 2b and a pair of bridging conductive members 3a and 3b. Each pair of parallel conducting members 2a and 2b forms two of the four sides of a turn of the coil 1 . Each pair of bridging conductors 3a and 3b forms the other two sides of a turn of the coil 1 . The rectangular spiral coil is formed by connecting adjacent parallel conductive members 2a and 2b to each other by bridging conductive members 3a and ...

Abstract

A laminated electronic component including at least one inductance element and produced froma laminate having electrical insulators and electrical conductors laminated alternately. The inductance element is formed as a helical coil having a plurality of turns each constituted by four sides. The inductance element has pairs of parallel conductor pieces and pairs of bridging conductor pieces. Each pair of parallel conductor pieces form two of the four sides of one turn of the coil. Each pair of bridging conductor pieces form the other two sides of one turn of the coil. Grooves are formed in the laminate to thereby form the parallel conductor pieces. The grooves are filled with an electrically insulating material. The bridging conductor pieces are formed on the electrically insulating material.

Description
