Abstract

PURPOSE:To form the gap on the propagation line of the surface wave without using any protective cap or the like, by coating the volatile low fusing point material on the substrate surface and molding them and then dispersing the volatile gas. CONSTITUTION:The surface wave device in which transmission and reception electrodes 2 and 3 are provided on substrate 1 is die-bonded to mount plate 5. Volatile material 9 of paraffin or the like is coated on the propagation line of the surface wave and then molded with the porous resin such as the phenol resin or the like. After this, the heating is given in the vacuum atmosphere, and as a result the volatile gas is dispersed through porous molded substance 8. In such way, the gap is formed on the propagation line. The molded substance doubles the absorber of the surface wave. In such process of gap formation, no use of the protective cap is required to reduce the working process.
