Abstract
An inductance component is disclosed. This inductance component includes base made of insulating material, coil section buried in base, and external electrode terminals electrically coupled to the ends of coil section. Stress buffering section is provided on the exposed interface between base and external electrode terminals, and this stress buffering section can ease the stress produced by the difference in thermal coefficients due to temperature changes. The foregoing structure thus allows improving the reliability of the inductance component with respect to a thermal shock.
Claims13
An inductive component comprising:
- a base made of insulating material;
- a coil section buried in the base;
- and
- an external electrode terminal electrically connected to an end of the coil section, the external electrode terminal including a first external electrode contacting the base and a second terminal electrode covering the first external electrode, wherein:
- a stress buffering section is provided between the base and the first external electrode,
- the stress buffering section includes a groove between the base and the first external electrode, and
- the first external electrode is exposed in the groove.
