Abstract
A piezoelectric device and a fabricating method thereof are provided. Variation of output frequency is suppressed by forming an organic resin to protect an IC chip that is mounted in a cavity of a container body, and damage that may occur to the IC chip during the mounting process is prevented. The piezoelectric device includes a container body, a crystal resonator, an IC chip and a cover body. A surface of the IC chip, which is a mounting surface for mounting to the container body, has bumps thereon for connecting to terminal pads of a circuit wiring pattern configured on a bottom surface of a bottom cavity of the container body, and the other surface of the IC chip has an insulating protective sheet adhered and fixed thereon.
