Claim:
1. An antenna module comprising: an insulative base layer that has first and second surfaces; an electrode formed on at least one surface of the first and second surfaces of the base layer to be capable of receiving or transmitting an electromagnetic wave in a terahertz band; and a semiconductor device that is mounted on at least one surface of the first and second surfaces of the base layer to be electrically connected to the electrode, and is operable in the terahertz band; wherein the electrode includes first and second conductor layers that constitute a tapered slot antenna having an opening, the opening has a width that decreases continuously or gradually from one end to another end of a set of the first and second conductor layers, a first slit is formed at the first conductor layer such that the first conductor layer is divided into a first device connection portion that is positioned at the other end of the first conductor layer and is electrically connected to the semiconductor device, and a first antenna portion that is not electrically connected to the semiconductor device, and a second slit is formed at the second conductor layer such that the second conductor layer is divided into a second device connection portion that is positioned at the other end of the second conductor layer and is electrically connected to the semiconductor device, and a second antenna portion that is not electrically connected to the semiconductor device, wherein the second device connection portion is spaced apart from the first device connection portion,
