PROBLEM TO BE SOLVED: To provide a meander line antenna the conductor pattern of which is formed in a meandered manner that can simply be adapted to a desired frequency band.SOLUTION: The meander line antenna formed by folding back the conductor pattern of a fold-back dipole antenna in a meandered manner employs a basic configuration including: a lower half part comprising a fold-back conductor pattern and formed in the middle part thereof with a feeding point 1 including an IC chip mounted on and connected to the part; an upper half part comprising a fold-back conductor pattern similar in shape to the lower half part; and a frequency adjustment part formed by respectively connecting the lower half part and the upper half part around the feeding point 1 as a center at an interval corresponding to a selected frequency by using patterns 2 each comprising a connection conductor, wherein the patterns 2 each comprising the connection conductor can be cut off or the fold-back conductor patterns at the outside of the patterns 2 each comprising the connection conductor can be disconnected.
