Patent ID: 7351918

Claim:
A surface-mount base for an electronic element, comprising: an insulative supporting member having a through hole; a plurality of lead terminals each having an element connecting terminal, a lead portion and a mounting terminal, the lead terminals being mounted to the supporting member with the lead portions passing through the through hole so that the element connecting terminals of the lead terminals face a top face side of the supporting member and the mounting terminals face a reverse face of the supporting member; and a sealing glass that is charged in the through hole of the supporting member for sealing the lead terminals in the through hole, wherein the supporting member is composed of a supporting frame having an outer wall that defines the through hole, the mounting terminal of each lead terminal runs across a reverse face of the supporting frame and extends along the outer face so as to form an externally facing portion and the lead portion of each lead terminal is disposed so as to face the inner face of the supporting frame, and the supporting frame is pressed between the lead portion and the externally facing portion, whereby the lead terminals are held on the supporting frame, and wherein the sealing glass is provided in a region between the element connecting terminals of the lead terminals and the reverse face of the supporting frame, with the element connecting terminals being exposed from the upper face of the sealing glass within an area of the through hole of the supporting frame.
