Abstract: Provided is a low temperature rapid curing type low elastic conductive adhesive which is useful as a conductive adhesive for component mounting in a field of FHE. A conductive resin composition contains (A) at least two types of urethane acrylate oligomers, (B) a radical polymerizable monomer, (C) a free radical generation curing agent, and (D) conductive particle. In the conductive resin composition, the component (A) preferably contains a high molecular weight urethane acrylate oligomer having a weight average molecular weight of 10,000 or more (A1), and a low molecular weight urethane acrylate oligomer having a weight average molecular weight of 9,999 or less (A2).

Abstract: There are provided a photosensitive resin composition, a cured product thereof, and a wiring structure body, an electronic component, a semiconductor device, and a camera module each including the cured product. This photosensitive resin composition is cured by irradiation with active energy rays, instead of by heat treatment at high temperatures. In this photosensitive resin composition, film loss after a development process is restrained. Furthermore, a miniaturized pattern can be accurately formed by photolithography. An aspect of the present invention is a photosensitive resin composition including components (A) to (C): (A) a modified polyphenylene ether represented by formula (1) and formula (2), (B) a silsesquioxane compound represented by formula (3), and (C) a photopolymerization initiator, a cured product thereof, and a wiring structure body, an electronic component, a semiconductor device, and a camera module each including the cured product.
