    Abstract: PROBLEM TO BE SOLVED: To reduce errors of magnitudes of openings of straight parts when forming the straight parts and tapered parts on silicon substrates different in plane directions, respectively.SOLUTION: A laminated substrate 53 formed by laminating a first active layer 23 whose plane direction is and a second active layer 24 whose plane direction is is formed at one face side of a BOX layer 51. A frame-shaped mask pattern layer 60a having a mask opening 60b is formed in a position in which a nozzle 12 on the second active layer 24 should be formed. Straight parts 20 of the nozzle 12 are formed in the mask opening 60b by forming a non-penetration hole 70 reaching one face of the BOX layer 51. A non-masked portion 24a of the second active layer 24 and the internal face of the non-penetration hole 70 are cover with thermal oxide films 72. An exposed portion 24b is formed on the second active layer 24 by removing the mask pattern layer 60a. Tapered parts 21 of the nozzle 12 are formed by crystal-anisotropy etching the second active layer 24 from the exposed portion 24b.
