PROBLEM TO BE SOLVED: To provide an antenna that suppresses core breakage during manufacturing and breakage due to an impact after installation as the antenna using the core of a magnetic material or dielectric, is easily manufactured, further has wide bandwidth and a high average gain in each frequency band and prevents degradation in a gain by securing isolation from a mounting substrate. SOLUTION: The antenna includes a rod-shaped magnetic core member made of the magnetic material or the dielectric, a cover member which covers at least part of a longitudinal direction side of the magnetic core member and has a plurality of legs for being fixed to a mounting substrate, a feeding terminal formed in the legs, and a winding part electrically connected to the feeding terminal, wherein in the cover member, a recess is formed at the legs therebetween, and the winding part winds the magnetic core member including the whole cover member.
