Abstract
Provided is a curable composition for inkjet and air cavity formation, the curable composition capable of forming a cured product layer having a high aspect ratio and capable of enhancing adhesiveness and sealability. A curable composition for inkjet and air cavity formation according to the present invention contains a photocurable compound having a (meth)acryloyl group or a vinyl group and having no cyclic ether group, and a thermosetting compound having no (meth)acryloyl group and having a cyclic ether group, in which a content of the thermosetting compound in 100 wt % of the curable composition for inkjet and air cavity formation is 5 wt % or more, and when a B-staged product is obtained by irradiating the curable composition for inkjet and air cavity formation with light having a wavelength of 365 nm at an illuminance of 2000 mW/cm, a viscosity at 40° C. of the B-staged product is 2.5×10Pa·s or more and 3.0×10Pa·s or less.
