PURPOSE:To prevent flux from intruding by providing a groove to a bottom surface and then by deriving a lead terminal from this groove. CONSTITUTION:Three lead terminals 2 are arrayed penetrating insulating sustrate 10. A couple of edge parts 12a and 12b are provided to two opposite length sides of the bottom surface of thin-plate base part 11. Then, lead terminals 2 are provided penetrating perpendicularly the groove formed in substrate 10 in its length-directional center. Then, edge parts 12a and 12b are made of an elastic body to protect the operation of tuning fork 3 from disturbance. |
