る。 The ceramic package of a conventional tuning fork crystal resonator is as shown in Fig. 1. Inside the ceramic package 1, there is an adhesive surface (die bonding part) 2 on the top surface of the mounting base for adhesively fixing the crystal resonator piece.
and electrode parts 3 and 4 are formed on both ends of the electrode parts 3 and 4. Since these are on the same plane, if there is a large amount of die bonding adhesive, it will protrude onto the electrodes 3 and 4, and the electrodes of the crystal resonator piece and the ceramic package. In some cases, the electrodes 3 and 4 could no longer be electrically connected. For this reason, it is necessary to precisely control the amount of adhesive, and this reduces the amount of adhesive, resulting in weak adhesive strength and poor impact resistance. The present invention improves these drawbacks and simplifies the die bonding process.
This provides a crystal resonator with good impact resistance.
以下、第２図〜第４図に従つて本考案の実施例
を示す。 Embodiments of the present invention will be shown below with reference to FIGS. 2 to 4.
第２図は水晶振動子片を接着固定する取付台の
接着面２に切欠き５を設けたものであり、水晶振

度も強くできる。 In Figure 2, a notch 5 is provided on the adhesive surface 2 of the mounting base for adhesively fixing the crystal resonator piece.
Since it flows into the electrode parts 3 and 4, it is possible to prevent it from protruding into the electrode parts 3 and 4, and the adhesive strength of the crystal resonator pieces can be strengthened.

晶振動子片を強固に接着できる。 FIG. 3 shows an embodiment in which small holes 6 are provided in the adhesive surface 2 of the crystal resonator piece. FIG. 4 shows yet another embodiment, in which a notch 7 having the same shape as that of FIGS. 2 and 3 is provided. Regarding these as well,
Excess adhesive is poured into the hole 6 or notch 7 to prevent it from overflowing to the electrode parts 3 and 4, and the crystal resonator piece can be firmly bonded with a sufficient amount of adhesive including the poured adhesive.
以上説明を加えた様に、本考案によれば、水晶
振動子片をダイボンドする際に、接着剤の量もそ

量も多くとれるため、振動子片の接着強度が強
く、耐衝撃性の良い水晶振動子を提供できる。 As explained above, according to the present invention, when die-bonding the crystal resonator pieces, the amount of adhesive does not require great precision, and there is no possibility of the adhesive protruding into the ceramic package. Moreover, since the amount of adhesive can be increased, it is possible to provide a crystal resonator with strong adhesive strength between the resonator pieces and good impact resistance.
