The subject of the present invention is to provide a radiation-sensitive composition that is excellent in storage stability and can form a cured film with excellent chemical resistance, a method of manufacturing a cured film, a semiconductor element, and a display element. A radiation-sensitive composition containing: a polymer component containing a first structural unit having an oxirane group and a second structural unit having a carboxyl group; a photosensitizer; selected from amine-based compounds, imidazole-based compounds, and isocyanate-based compounds At least one compound in the group consisting of; and a solvent; and relative to all the structural units constituting the polymer component, the content of the first structural unit is more than 20% by mass and 65% by mass or less, and the content of the second structural unit is The ratio is more than 5% by mass and 25% by mass or less, and the solvent contains 20% by mass or more of the total solvent contained in the radiation-sensitive composition. The hydrogen bond term dH of the Hansen solubility parameter is as high as 10.0 or more. dH solvent. |
