whereinthe coil conductors of the main line are divided into a first main line and a second main line disposed on different dielectric layers in the laminate block;
the coil conductors of the sub-line are divided into a first sub-line and a second sub-line on different dielectric layers in the laminate block;
the first main line, the second main line, the first sub-line, and the second sub-line are arranged in order of the first main line, the first sub-line, the second sub-line, and the second main line or in order of the first sub-line, the first main line, the second main line, and the second sub-line in a lamination direction of the dielectric layers in the laminate block;
the first main line and the first sub-line are coupled to define a first coupling portion;
the second main line and the second sub-line are coupled to define a second coupling portion;
a ground conductor is provided on a dielectric layer of the laminate block between the first coupling portion and the second coupling portion;
each of the first main line, the second main line, the first sub-line, and the second sub-line is further divided into at least two divided coil conductors on a dielectric layer including a corresponding one of the first main line, the second main line, the first sub-line, and the second sub-line;
the ground conductor is divided into at least two divided ground conductors that are located at opposite ends of the laminate block and do not overlap each other in a planar view along the stacking direction.

Abstract
A directional coupler includes in a laminate block, a first main line, a first sub-line, a second sub-line, and a second main line sequentially provided in a lamination direction of layers. Further, each of the first main line, the first sub-line, the second sub-line, and the second main line is divided into at least two divided coil conductors. Furthermore, at least two divided ground conductors are provided between the first sub-line and the second sub-line.
