Abstract:
1. A curable resin composition comprising: (I) 100 parts by weight of a curable resin; (II) 10 to 1200 parts by weight of an inorganic filler; and (III) 1 to 100 parts by weight of an organic filler having an elastic modulus of 1 to 2000 (MPa) as measured by using a tensile tester with a sample produced by moulding the organic fillers at 150 to 200° C. for 10 minutes using a vacuum pressurization press machine and an average particle diameter of 0.01 to 10 μm, wherein a content weight ratio of the components (II) to (III) is 1 to 41, wherein the curable resin (I) contains (I-1) a photo-setting resin having no aromatic ring in a molecule, and the resin (I-1) is selected from the group consisting of (I-1-i) a reaction product of an acid group-containing acrylic resin obtained by polymerizing an ethylenic unsaturated acid as an essential monomer and alicyclic epoxy group and/or oxetane group-containing unsaturated compound, (I-1-iV) one obtained by reacting a copolymer of alkyl(meth)acrylate and glycidyl(meth)acrylate with (meth)acrylic acid and further reacting the copolymer with a saturated or unsaturated polybasic acid anhydride, and (I-1-V) one obtained by reacting a copolymer of hydroxyalkyl(meth)acrylate, alkyl(meth)acrylate and glycidyl(meth)acrylate with (meth)acrylic acid and further reacting the copolymer with the saturated or unsaturated polybasic acid anhydride.
