PURPOSE:To improve the durability and reliability by adhering and laminating an antenna conductor with a protection layer, a dielectric plate and a ground conductor by an adhering sheet mutually. CONSTITUTION:The antenna conductor 13 is formed on the protection layer 11 by screen print. On the other hand, while an adhering sheet 18 is laminated on the ground conductor 15 mutually, heat treatment of 170-300 deg.C is applied by a heat roll or hot press to form an one-piece forming of the adhering sheet 18 and the ground conductor 15. After an adhering sheet 16, a polyolefin resin 17 and the ground conductor 15 with the adhering sheet 18 are laminated on the antenna conductor 13 with the protection layer 11 in this order an the laminated body is pressed thermally at a temperature lower than that of the said heat treatment such as 160 deg.C under a pressure condition of 3kg/cm<2>. Thus, since the excellent peeling durability is obtained, the microstrip line antenna with high reliability is obtained. |
