Abstract
A metallized ceramics substrate including: a ceramics body; a wiring pattern formed on one surface of the ceramics body; and a lead electrically-connected to the wiring pattern. The ceramics body has a through-hole, the lead penetrates the through-hole and sticks out from another surface of the ceramics body, and the lead is fixed by filling an electroconductive filler between the lead and the through-hole for keeping airtightness. The metallized ceramics substrate does not cause a problem of interlayer peeling and is excellent in airtightness and electric conductivity.
