Abstract: In a built-in coil substrate, coil conductor patterns are provided on insulating base materials. Coil interlayer connection conductors, which provide interlayer connection between the coil conductor patterns, are provided on the insulating base materials and made of conductive paste. First and second external electrodes are provided on a first principal surface of a multilayer body. One of the coil conductor patterns is connected to the first external electrode by first-external-electrode connection conductors made of the conductive paste. Another one of the coil conductor patterns is connected to the second external electrode by a second-external-electrode connection conductor. The second-external-electrode connection conductor is a metal film provided in a through hole that extends through the multilayer body in a stacking direction in which the insulating base materials are stacked.

Abstract: A multilayer substrate includes a differential line including first and second line conductors provided on or in a laminated body including base material layers. The differential line includes line portions and a connecting portion that connects the line portions. The connecting portion includes first parallel conductors extending in parallel or substantially in parallel with each other, first interlayer connecting conductors that connect the first parallel conductors in parallel, and connect the first line conductor to the first parallel conductors, second parallel conductors extending in parallel or substantially in parallel with each other, and second interlayer connecting conductors that connect the second parallel conductors in parallel, and connect the second line conductor to the second parallel conductors. The first parallel conductors cross the second parallel conductors as viewed in a laminating direction of the base material layers.

The first and second portions have different thicknesses so that a step is provided therebetween. The insulating board includes a first land conductor on a first mounting surface of the first portion at a side at which the step is provided, a second land conductor on a second mounting surface of the second portion at the side at which the step is provided, and an insulating protection film on the first mounting surface so that a portion of the first land conductor is exposed and another portion of the first land conductor is covered. An electronic component is soldered to the first land conductor. Another electronic component is joined to the second land conductor by an anisotropic conductive film that covers the second land conductor.

Abstract: An antenna includes antenna coil having a magnetic-material core and a coil conductor. The antenna coil is arranged toward a side of a planar conductor, such as a circuit board. Of the coil conductor, a first conductor part close to a first main face of the magnetic-material core and a second conductor part close to a second main face of the magnetic-material core are provided such that the first conductor part is not over the second conductor part in view from a line in a direction normal to the first main face or the second main face of the magnetic-material core. In addition, a coil axis of the coil conductor is orthogonal to the side of the planar conductor.

Abstract: A process of manufacturing a multilayer circuit board includes patterning insulating substrates on which conductors are formed to provide a signal conductor, a first ground conductor, and a second ground conductor. The insulating substrates including the signal conductor, the first ground conductor, and the second ground conductor are stacked and thermally crimped to form a laminate. An interlayer connection conductor is formed on a surface of the laminate by a Laser Direct Structuring process.
