Title:

ELECTRONIC COMPONENT, PIEZOELECTRIC OSCILLATOR, RECOGNITION METHOD OF BUILT-IN ELECTRONIC COMPONENT AND RECOGNITION METHOD OF PIEZOELECTRIC VIBRATOR

Document Type and Number:

Japanese Patent JP2005123246

Kind Code:

A

Abstract:

To provide an electronic component which identifies a built-in electronic component mounted in a mold material from the outside of the mold material, a piezoelectric oscillator, a recognition method of the built-in electronic component, and the recognition method of a piezoelectric vibrator.

The electronic component 30 has the built-in electronic component 10, and a molding part covering the built-in electronic component 10 by the mold material 46. The surface of the built-in electronic component 10 is coated with an X-ray absorption material, and an indicator for identifying the built-in electronic is formed. By irradiating such an electronic component 30 with an X-ray, the indicator formed in the built-in electronic component 10 is recognized.
