Patent ID: 8013257

Claim:
An electronic component, comprising: a ceramic substrate; a passive element portion provided on the ceramic substrate; an insulator layer provided over the passive element portion and comprising a through-hole; a lead terminal fitted in the through-hole in the insulator layer and electrically connected to the passive element portion; and an external connection terminal electrically connected to the lead terminal, wherein the insulator layer comprises a first face which is in contact with the passive element portion, a second face on the side opposite the passive element portion, and a third face connecting the first face and the second face and constituting a peripheral face of the insulator layer, the external connection terminal is in contact with the lead terminal and the second and third faces of the insulator layer, and in a cross-section in a thickness direction of the ceramic substrate where the through-hole is present, a peripheral boundary line, which is the boundary line closer to the third face of two boundary lines between the lead terminal and an internal surface of the through-hole, 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 peripheral boundary line on the side of the first face being taken as a fixed point.
