PROBLEM TO BE SOLVED: To provide a multiband antenna apparatus for an automobile which covers frequency bands ranging from 140 kHz of AM radio as a lower limit to 1800 MHz for mobile phones as an upper limit, improves reliability related to connections, and is economically advantageous. SOLUTION: On the surface of a dielectric support (10) of 35 mm×130 mm mounted on an automobile, 12 loops of a thin conductor pattern are provided as an antenna body (20). The antenna body (20) comprises an electronic circuit (5) constituted of a reception/transmission module (30) made to match an electromagnetic wave signal having a frequency positioned within a predetermined frequency band, and a matching module (40) for making the antenna body (20) match the predetermined frequency band. The electronic circuit (5) is connected to a receiver/transmitter mounted on the automobile, and the electronic circuit (5) is attached to the dielectric support (10) and molded as a single body.
