Title:
CIRCUIT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2020/246118
Kind Code:
A1
Abstract:
This circuit element (101A) comprises: a laminate body (1) of an insulation base material; a first coil conductor that is provided inside the laminate body (1); and a first external electrode (EE1), a second external electrode (EE2), and a ground electrode (EG1) that are provided on the outer surface of the laminate body (1). The first coil conductor has a winding axis in the lamination direction of the insulation base material, the first coil conductor is connected to the first external electrode (EE1), the second external electrode (EE2), and the ground electrode (EG1), and the second external electrode (EE2) is formed along the side surface of the laminate body (1). An additional capacitance is formed between the second external electrode (EE2) and the first coil conductor as the first coil conductor and a second part (SP), which is a wide portion of the second external electrode (EE2), get close to each other, the second external electrode (EE2) has first parts (FP1, FP2) that have different widths in the layer direction of the insulation base material, and the second part (SP), and the width of the second part (SP) is greater than the widths of the first parts (FP1, FP2).
