MANUFACTURING METHOD OF WIRING BOARD, MANUFACTURING METHOD OF ELECTRON SOURCE, MANUFACTURING METHOD OF IMAGE DISPLAY APPARATUS AND IMAGE REPRODUCING APPARATUS

摘要

A manufacturing method of a wiring board, a manufacturing method of an electron source, a manufacturing method of an image display apparatus, and an image reproducing apparatus are provided to improve connection reliability of a wire formed in a groove and an electrode installed on a substrate surface near to the groove. A substrate(A) has an adjacent region near to a groove. A first wire(B) has a first portion(4) and a second portion(5) extended from the first portion. The first portion is formed on a first region(711) in the groove. The second portion is formed on a second region(712) that is a part of the adjacent region. The substrate having the groove is prepared. A contact angle of the second region is differentiated from that of a third region that is another part of the adjacent region. The third region encloses the second region with the groove. A conductive paste is applied to the groove and to a part of the adjacent region.
