PROBLEM TO BE SOLVED: To provide a crystal resonator which reduces a temperature difference between actual temperatures of at least two crystal elements and a temperature set based on temperature information obtained by a thermo-sensitive device and thereby properly conducts temperature correction at oscillatory frequencies of the crystal elements.SOLUTION: A crystal resonator includes: a rectangular substrate 110a; a frame body 110b provided on an upper surface of the substrate 110a; a mounting frame body 160 provided on a lower surface of the substrate 110a; an electrode pad 111 provided on the upper surface of the substrate 110a in the frame body 110b; a connection pad 113 provided on the lower surface of the substrate 110a in the mounting frame body 160; a first crystal element 120 and a second crystal element 130 mounted on the electrode pad 111; a thermo-sensitive device 150 mounted on the connection pad 115 by a conductive joint material 180; and a lid body 140 joined to an upper surface of the frame body 110b. |
