Abstract
An IC tag according to the present invention includes: an IC chip (); a dipole antenna () for electrically transmitting and receiving information stored in the IC chip (); and a sheet-shaped substrate () that supports the IC chip () and the dipole antenna (). In this IC tag, 0.1≤R/L≤2.5 is satisfied, where R is a resistance value between two ends (S, S) of the dipole antenna () and L is a length of a path that connects the two ends (S, S) of the dipole antenna () while extending along the dipole antenna () without passing through the IC chip ().
