Abstract
Provided herein are a jet hole plate, a liquid jet head, a liquid jet recording apparatus, and a method for manufacturing a jet hole plate that can achieve a long life. A jet hole plate according to an embodiment of the present disclosure is a jet hole plate for use in a liquid jet head. The jet hole plate includes a metal substrate having provided therein a plurality of jet holes. The metal substrate has a principal surface having outlets for the jet holes. The principal surface has a surface roughness (arithmetic mean roughness Ra) that is smaller in outlet edge regions of the jet holes than in surrounding regions around the outlet edge regions.
