摘要

An antenna device (1) is provided with a feeder coil (21) and a housing (11) including a metal housing part (12). The metal housing part (12) has a main surface, a side surface connected to the main surface, and a notched part (14) formed in the side surface. The feeder coil (21) is disposed so as to be joined by a magnetic field with the metal housing part (12) inside the housing (11), and a winding center part forms a coil opening part (22). The feeder coil (21) is disposed in proximity to the notched part (14), the coil opening part (22) being oriented towards the region in which the notched part (14) is formed.
