PROBLEM TO BE SOLVED: To provide a piezoelectric device which is easily manufactured, can be reduced in height, and prevents deterioration in oscillation characteristics caused by wiring resistance. SOLUTION: The device is provided with a piezoelectric resonation element 30; columnar conductive members 20 used as external terminals; an integrated circuit element 10 formed by providing a mounting pad 13 for mounting the piezoelectric resonator 30, and an electrode pad 11 for mounting the conductive member 20 on the same surface; and a lid 40 having a concave portion 41 for covering the piezoelectric resonation element 30. The lid 40 is positioned nearer to the integrated circuit element 10 side than to the end 21 of the conductive member 20. COPYRIGHT: (C)2007,JPO&INPIT
