摘要： A compact antenna comprises a core which is a hard linear member having a predetermined shape corresponding to resonance characteristic, a conductor film which covers at least a portion of an outer surface of the core and which has higher electric conductivity than that of the core, and a substrate which closely surrounds and holds the outer surface of the core covered with the connection film. A film thickness of the conductor film is equal to a skin depth and thus, it is possible to inexpensively maintain reliability, and to prevent radiation efficiency from being lowered.

摘要： An optical ferrule is a molding of a resin composition comprising a base resin, silica, and whisker, as essential components. The resin composition has a melt viscosity of 300 to 600 [Pa×sec.] when measured at a shear rate of 900 [1/sec.] at a temperature of 340° C. by using a capillary having a diameter of 0.1 mm and a depth of 30 mm as defined by JIS-K-7199. Preferably, the base resin is a linear polyphenylene sulfide resin, and 250 to 300 parts by weight of silica and 10 to 70 parts by weight of whisker are blended with 100 parts by weight of the linear polyphenylene sulfide resin.
