Japanese Patent JP4450071
Kind Code:
B2
Abstract:
The present invention provides an electronic component which is capable of effectively suppressing the characteristic deterioration of the passive element portion. An electronic component comprises a ceramic substrate, a passive element portion on the substrate, an insulator layer which is provided over the passive element portion and comprises a through-hole, a lead terminal which is fitted in the through-hole of the insulator layer and electrically connected to the passive element portion, and an external connection terminal which is electrically connected to the lead terminal. The insulator layer comprises a first face on the side of the passive element portion, a second face on the side opposite the passive element portion, and a third face which connects the first face and the second face and constitutes the peripheral face of the insulator layer, the external connection terminal is in contact with the lead terminal and the second face and the third face of the insulator layer. In a cross-section of the through-hole in a thickness direction of the substrate, a boundary line between the internal surface of the through-hole and the lead terminal is inclined in a direction moving away from a region of the third face with which the external connection terminal is in contact with an end of the boundary line on the side of the first face being taken as a fixed point.
