PURPOSE:To provide the titled adhesive capable of facilitating the bonding to a part to which a temporary fixing jig cannot be applied and resistant of the flow of adhesive out of the necessary part in heat-curing, by adding a magnetic material and a curing agent to a curable thermosetting resin which is solid at normal temperature, and pulverizing the mixture. CONSTITUTION:A curable thermosetting resin which is solid at normal temperature (preferably an epoxy resin having a number-average molecular weight of 2,000-50,000 and an epoxy equivalent of 120-5,000) is mixed with a magnetic material (preferably iron, etc.) and a curing agent (e.g. diethylenetriamine), kneaded, cooled and pulverized to obtain the objective adhesive. The powdery adhesive or a molded article produced by the injection molding, etc., of the adhesive is placed on the part to be bonded, and temporarily fixed by external magnetic field. As an alternative method, the powdery adhesive or the molded article of the adhesive is magnetized, attached to the adhered attractable by magnetic force and cured to complete the bonding.
