1. An element comprising:
an antenna array that includes a first antenna and a second antenna arranged in this order along a first direction, and a third antenna and a fourth antenna arranged in this order along the first direction, wherein the first antenna and the third antenna are arranged in this order along a second direction that intersects the first direction;
a first coupling line for coupling the first antenna and the second antenna;
a second coupling line for coupling the third antenna and the fourth antenna; and
a bias line for suppling a bias voltage to the first antenna, the second antenna, the third antenna, and the fourth antenna and that includes a first part and a second part,
wherein the first antenna, the second antenna, the third antenna, and the fourth antenna each produce or detect a terahertz wave,
wherein the first part passes between the first antenna and the third antenna, and passes between the second antenna and the fourth antenna, in a plan view,
wherein the second part passes between the first antenna and the second antenna, and passes between the third antenna and the fourth antenna, in the plan view, and
wherein the second part intersects the first part.
