INK JET RECORDING HEAD AND METHOD OF MAKING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an ink jet recording head and a method of making the same wherein the processing and assembling can be readily executed at low cost, the head can be miniaturized and bubbles hardly enter a fluid passage. SOLUTION: The ink jet recording head is equipped with a head body for ejecting ink and the fluid passage for introducing the ink supplied from an ink tank to the head body. The ink jet recording head comprises a fluid-passage forming base 29 having a groove for forming the fluid passage 32 and a sealing plate 31 for sealing an opening section of the groove by being bonded to the fluid-passage forming base 29, thereby facilitating the processing and the assembling of the ink jet recording head and miniaturizing the ink jet recording head.
