Abstract
An ink jet recording head includes a flow passage for a liquid for cooling a recording element substrate. The flow passage is provided inside a support plate that supports the recording element substrate along a recording element array of the recording element substrate. The shortest distance between a recording element and the flow passage at the end of the support plate is larger than the shortest distance between a recording element and the flow passage in the middle of the support plate.
