Abstract: The adhesive sheet includes an adhesive layer (A1L) in solid form at 18° C., wherein the adhesive layer (A1L) contains an epoxy resin, at least one surface of the adhesive layer (A1L) has a tackiness agent region (A2R) formed by partially providing a tackiness agent (A2), and a region where the tackiness agent region (A2R) is not formed on the surface is an adhesive-layer-exposed region (A1LR) where a surface of the adhesive layer (A1L) is exposed. This adhesive sheet has excellent temporary fixability at the time of sticking (a characteristic that exhibits the tackiness force necessary for temporary fixation) and adhesive force after heat curing.
