PROBLEM TO BE SOLVED: To improve the accuracy of antenna characteristics in an antenna device including an antenna substrate and a control board.SOLUTION: An antenna device (10) includes: a control board (20) having a wireless communication circuit (28); and an antenna substrate (30) which has at least one base (32) made of an electrically insulating material and at least one antenna element (34) disposed on the base (32) and electrically connected to the wireless communication circuit (28) and is fixed to one surface (20a) of the control board (20). The base (32) is fixed in close contact with the one surface (20a) of the control board (20) by injection molding. The antenna substrate (30) has the antenna element (34) on a rear surface (32b) opposite to that surface (32a) of the base (32) which is in close contact with the one surface (20a). |
