PROBLEM TO BE SOLVED: To provide a GPS antenna system which is made small in size and light in weight by unnecessitating a surge registance circuit without being affected by static electricity in the atmosphere by housing a GPS antenna 10 in the space of surer airtight structure. SOLUTION: The GPS antenna 10 is arranged on a base member 16, a radome 18 for covering the antenna 10 and the member 16 are formed by resin, a groove 16a for surrounding the antenna 10 is formed on the member 16, and a projected line 18a to be inserted/engaged into/with the groove 16a is formed on the radome 18. The projected line 18a is inserted/engaged into/with the groove 16a in the assembled state of the radome 18 and welded by ultrasonic welding to surround the antenna 10 by airtight structure using the base member 16 and the radome 18.
