Abstract: An electronic apparatus includes a rectangular or substantially rectangular plate-shaped housing including a first side and a second side which are long sides and a third side and a fourth side which are short sides, and an antenna device. The antenna device includes a first coil including a first coil conductor and a second coil including a second coil conductor. A portion of the first coil overlaps with the second coil opening, a portion of the second coil overlaps with the first coil opening, a straight line connecting a center of gravity of the first coil opening and a center of gravity of the second coil opening intersects with the third side and the fourth side, and the center of gravity of the second coil opening is closer to the third side than the center of gravity of the first coil opening.
