PROBLEM TO BE SOLVED: To provide a negative photoresist composition by which an inkjet printer head with an improved durability can be manufactured, a method for manufacturing the inkjet printer head using the negative photoresist composition, and the inkjet printer head. SOLUTION: The negative photoresist composition includes a prepolymer including oxetane acting groups in repeated units and having bisphenol-A based skeletons, a cationic photoinitiator, and the solvent, the method for manufacturing the inkjet printer head with few thickness variation and improved durability is constituted by using the photoresist composition, and the inkjet printer head is constituted by manufacture on the method.
