Abstract: A filler for resinous composition is contained and used in resinous composition constituting electronic packaging material for electronic device, and includes: a filler ingredient including a crystalline siliceous material with a crystal structure made of at least one member selected from the group consisting of type FAU, type FER, type LTA, type MFI and type CHA, and/or type MWW, wherein: the filler ingredient is free of any activity when evaluated by an “NH3-TPD” method; and includes the crystalline siliceous material in an amount falling in a range allowing the filler ingredient to exhibit a negative thermal expansion coefficient. The filler ingredient may further be free of a surface in which silver, copper, zinc, mercury, tin, lead, bismuth, cadmium, chromium, cobalt and nickel are exposed.

Abstract: A silicone-coated filler comprises: a particulate material mainly composed of an inorganic oxide formed by oxidizing a predetermined element; a first silicone structure bonded to a surface of the particulate material by way of a “-‘the predetermined element’-OSi—” structure; and a second silicone structure including a cross-linking structure with a carbon-carbon structure directly bonded to a silicon atom of the first silicone structure, and a polysiloxane structure bonded to the cross-linking structure.
