An antenna module (100) according to the present invention is provided with: a dielectric substrate (130) which has a multilayer structure; a first radiation electrode (121) and a ground electrode (GND), which are arranged on the dielectric substrate (130); and a second radiation electrode (150) which is arranged in a layer that is positioned between the first radiation electrode (121) and the ground electrode (GND). The first radiation electrode (121) is a power feed element to which a high frequency power is supplied. If the antenna module (100) is viewed in plan from the normal direction ofthe dielectric substrate (130), the first radiation electrode (121) and the second radiation electrode (150) overlap with each other at least partially. The thickness of the second radiation electrode (150) is larger than the thickness of the first radiation electrode (121). 天线模块(100)包括：介电体基板(130)，其具有多层构造；第1辐射电极(121)和接地电极(GND)，其配置于介电体基板(130)；以及第2辐射电极(150)，其配置于第1辐射电极(121)与接地电极(GND)之间的层。第1辐射电极(121)是被供给高频电力的供电元件。在从介电体基板(130
