<p>PURPOSE: To reduce a danger of a mechanical damage of a connection part substantially by providing at least one connection recessed part to each connection area, and making a conductive connection element in contact with a metallic film so as to connect the element to a substrate through the connection recessed part. CONSTITUTION: Connection elements 10, 11 cover connection areas 6, 7. The connection elements are in contact with a metallic film 3 at an end region 12 and engage with connection recessed parts 8, 9, and a substrate 2 is in contact with a surface 13 thereat. The connection elements are coated in a form of thick film paste by, e.g. a screen print method and finally baked. Metallic powder, especially silver palladium mixture or gold palladium mixture, glass flit powder or its carrier is adopted for the thin film paste. Then, the thick film paste is baked in a continuous heat furnace in a temperature range of 750-950 deg.C.</p> |
