PROBLEM TO BE SOLVED: To obtain an antenna device in which an in-vehicle antenna can be disposed at a desired position in a vehicle. SOLUTION: The antenna device 1 is configured so that a first antenna 11 where a first coil 21 and a first capacitor 31 are connected in series and a second antenna 12 where a second coil 22 and a second capacitor 32 are connected in series are formed so that turning directions indicated with arrows of mutual high frequency currents i1, i2 flowing to the first and second coils 21, 22 are inverse to each other and their central axes become parallel, and a fixed resistor 5 being a current regulation means is connected to the second coil 22 at the side of the second antenna 12.
