Abstract: Provided is a photocurable adhesive with which curing by direct irradiation of laser light is possible with almost no occurrence of surface carbonization and which is capable of satisfactory curing even when the coating thickness is increased. A photocurable adhesive, which is cured by irradiation of laser light, is provided. The curable adhesive contains an epoxy adhesive component, a light-absorbing component for thermal curing of the epoxy adhesive component by absorption of laser light, and an inorganic filler. The content of the light-absorbing component is 0.1 mass % or less. The pre-curing thermal conductivity of the photocurable adhesive is at least 0.2 W/m·K and the post-curing thermal conductivity is at least 0.5 W/m·K.
