Title:
LIQUID DISCHARGE HEAD AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2008006812
Kind Code:
A
Abstract:
To hermetically seal more surely a gap between a back surface of a liquid discharge substrate and a front surface of a support member, and an electrode portion without adversely affecting discharge performance.
A first sealing resin 510 coats the support member 200 in "U shape" so as to surround the vicinity of both the tip ends of a liquid supply port 210. In addition, a liquid discharge substrate 400 is mounted over the first sealing resin 510, and electrically connected to an electrode pad 220 of the support member 200. Furthermore, a second sealing resin 520 coats the entire periphery of the liquid discharge substrate 400 on the support member 200.
