Abstract
(EN)
The present invention improves the intensity and directionality of a radio wave without increasing device weight. This radar device (1) is provided with: a substrate (10) provided with an antenna (13) on one main surface (11) thereof; and a resin horn (20) arranged on the one main surface (11) of the substrate (10), wherein the horn (20) is provided with a wave guide path (23) formed at a position corresponding to the antenna (13) so as to have a width increasing toward the direction away from the one main surface (11) of the substrate (10), and a shield layer (29) is formed of a metal film (28) on a wall surface (26) of the horn (20) in which the wave guide path (23) is formed.
