Description
Claims (1)
- 矩形状とした水晶片と、前記水晶片の両主面に設けられて対向する励振電極と、前記励振電極から長手方向の一端部両側に延出して互いに反対面に折り返された引出電極と、前記水晶片の引出電極の延出した一端部両側の端面を含む一主面のみが導電性接着剤によって固着される水晶端子を有する実装基板とを備えた表面実装用の水晶振動子において、
前記励振電極は細長の同一幅として両主面間の中央領域にて前記水晶片の長辺に対して斜め方向に形成され、対向する前記励振電極は互いに直交するとともに前記引出電極は前記励振電極よりも幅狭とし、
前記一主面の励振電極からの引出電極は、前記一主面の励振電極の両端側から、前記一主面の長辺まで一直線上に延出して前記一主面の前記長辺に沿って前記水晶片の一組の対角部に延出してそれぞれ他主面に折り返され、
前記他主面の励振電極からの引出電極は、前記他主面の励振電極の両端側から、前記他主面の長辺まで一直線上に延出して前記他主面の前記長辺に沿って前記水晶片の他組の対角部に延出してそれぞれ一主面に折り返されたことを特徴とする水晶振動子。
