PURPOSE:To prevent a dielectric from being melted due to heat and to improve the reliability by providing a supporting member made of materials with a high melting point, which penetrates a ground conductor and the dielectric so as to face a conductor and soldering a lead wire for communicating said member and the conductor on the conductor at the surface opposite to the dielectric. CONSTITUTION:The microstrip line antenna 11 is constituted by laminating a synthetic resin thin film 12, an antenna conductor 13 receiving a radio wave, the dielectric 14 and the ground conductor 15 made of a metallic foil. The supporting member 18 made of the material with a high melting point is provided in such a way that it penetrates the dielectric 14 and the ground conductor 15 and faces the conductor 13. Said member is made columnar. The lead wire 16 is inserted into the member 18 and the conductor 13, and one end of the lead wire 16 and the conductor 13 are soldered with a solder 17 on the surface opposite to that where the conductor 13 faces the dielectric 14. Thus the dielectric will not be melted by heat, and the reliability of the line antenna 11 can be improved.
