本发明提供一种可提高接着剂硬化而得之接着剂层之厚度精度，进而可不易于接着剂层产生孔隙之喷墨用光及热硬化性接着剂。 本发明之喷墨用光及热硬化性接着剂包含光硬化性化合物、热硬化性化合物、光聚合起始剂、及热硬化剂，且以365nm下之照度成为100mW/cm2之方式对接着剂照射累计光量1000mJ/cm2之光而获得B-阶段化接着剂时，上述B-阶段化接着剂于25℃下之弹性模数为5.0×102Pa以上且8.0×104Pa以下。

Provided is an inkjet photo- and heat-curable adhesive capable of increasing the thickness precision of an adhesive layer in which the adhesive is cured and also capable of making it more difficult for voids to occur in the adhesive layer. This inkjet photo- and heat-curable adhesive comprises a photocurable compound, a heat-curable compound, a photopolymerization initiator and a heat-curing agent. When light of 1000 mJ/cm2 cumulative light quantity is irradiated on the adhesive so that the irradiance at 365 nm is 100 mW/cm2 and a B-staged adhesive is obtained, the elastic modulus at 25 DEG C of the B-staged adhesive is 5.0 x 102 Pa to 8.0 x 104 Pa.
