PURPOSE:To prevent the characteristic variation by connecting a lead frame and a surface wave element, after an insulating resin is coated to a surface wave element, bending a shield terminal to the rear surface side of a shield terminal and coating the conductive resin to the outer circumference of the insulating resin. CONSTITUTION:After an insulating resin 5 is coated to a surface wave element 1 to connect a lead frame 2, until the interval dimension of the tip of a shield terminal 4 and the insulating resin 5 comes to be the 1/2 or below of the interval dimension of the base end of the shield terminal 4 and the insulating resin 5, a shield terminal 5 is bent to the rear surface side of the surface wave element 1 and the tip of the shield terminal 4 is made into approximately the adhesion condition to the insulating resin 5 while a spring characteristic is held. By coating a conductive resin 7 to the outer circumference of the insulating resin 5 while the shield terminal 4 is included, the shield terminal 4 is buried to the conductive resin 7, the shield terminal 4 is not separated from the insulating resin 7 and connected through the conductive resin 7 without fail. Thus, the shieldability is improved and a stable characteristic can be obtained.
