Abstract

PURPOSE:To execute the cheap resin sealing by applying and forming a bonding layer it an element circumference, covering a heat resistance sheet on an upper part, hardening the bonding layer and simultaneously, forming a space at the element circumference. CONSTITUTION:After a bonding layer 27 is applied to an island part 23 of the circumference of an element 21, a heat resistance sheet 28 is coverred on the upper part of the bonding layer 27. At this time, the upper part of the bonding layer 27 is formed at a position higher than the surface of the element 21. Thereafter, by irradiating the ultraviolet ray by an ultraviolet ray irradiating device 29 from the upper part of the heat resistance sheet 28, the bonding layer 27 is hardened and the heat resistance sheet 28 is bonded. In this condition, a space 30 is formed on the surface of the element 21. Further, while a space 30 is formed at the element 21, it is inserted into an injection molding die, after the facing sealing formation is executed by a thermoplastic resin, the extra part of a COM lead 22 is cut, respective terminals 25 are bent to the bottom part of a facing body 32 and a chip type surface acoustic wave filter corresponding to the surface mounting is manufactured.
