Abstract: A method of manufacturing an inductor component includes preparing an insulating paste that is photosensitive and that includes a filler material composed of quartz, a glass material and a resin material, and a conductive paste, forming a first insulating layer by applying the insulating paste, and exposing the first insulating layer in a state where a first portion of the first insulating layer is shielded by a mask. The method further includes removing the first portion of the first insulating layer to form a groove at a position corresponding to the first portion, applying the conductive paste in the groove to form a coil conductor layer in the groove, and applying the insulating paste on the first insulating layer and the coil conductor layer to form a second insulating layer.

Abstract: A photosensitive resin composition which is high in thermal decomposition property of a photocured product thereof even in a case of being subjected to heat treatment in a non-oxygen atmosphere and is less likely to generate a residue of carbon and a photosensitive paste composed of the same are provided. The composition contains (a) a photopolymerization initiator, (b) an acryl monomer, and (c) polyalkylene carbonate, in which a ratio of polyalkylene carbonate to a total amount of the acryl monomer and polyalkylene carbonate is not lower than 50 weight % and not higher than 90 weight %. Polypropylene carbonate is used as polyalkylene carbonate. The photosensitive paste is obtained by blending the photosensitive composition, a solvent, and inorganic powders. Insulating inorganic material powders or conductive metal powders are employed as the inorganic powders.
