<p>In a mounting board (20a,20b), two through-holes (22a,22b) are formed which are used for inserting both ends of a supporting member (18a,18b) for a vibrator (12). On a surface of the mounting board (20a,20b), a ground conductor pattern (24a,24b) is formed. In the ground conductor pattern (24a,24b), two portions of arcs (28a) that the ground conductor pattern is removed are formed on respective peripheries of the two through-holes (22a,22b). Furthermore, on the mounting board, (20a,20b) two connecting conductor patterns (26a,26b) are formed on surfaces of portions defined two through-holes and so on, so as to extend from the ground conductor pattern. Both ends of the supporting member (18a,18b) for the vibrator (12) are respectively inserted into two through-holes (22a,22b) and soldered to two connecting conductor patterns (26a,26b). <IMAGE></p> |
