An ink jet recording head and a process for producing the same, and an ink jet recording apparatus are provided that improve the printing performance and also improve the production efficiency. A conjugated bodyformed by conjugating silicon wafersandis cut, whereby nozzlesare opened, and cutting into head chip units is carried out. At this time, deep groovesare formed on the surface of the silicon waferby anisotropic etching, and they are penetrated by etching on the opposite side. Groovesare formed on the silicon waferby using the thus penetrated deep groovesas a mask.
