PROBLEM TO BE SOLVED: To provide an antenna component which can possess directivity in multiple directions and/or cope with a plurality of frequency bands, and thereby contributes to compaction. SOLUTION: The antenna component includes a wiring board having first through fourth wiring layers, first through third insulating layers interposed between these wiring layers, respectively, first through third interlayer connectors which can connect between the wiring layers electrically by penetrating the first through third insulating layers, respectively, wherein a first antenna conductor pattern is formed in the helical shape having an axis in the direction parallel with the first through third insulating layers by using the first wiring layer, the first interlayer connector, the second interlayer connector, and the third interlayer connector, and the fourth wiring layer; and a second antenna conductor pattern is formed in the helical shape, having an axis in the direction intersecting the axis of the first antenna conductor pattern perpendicularly by using the second wiring layer, the second interlayer connector, and the third wiring layer.
