    Abstract: Provided is a thermosetting resin composition which exhibits excellent workability, and which is capable of obtaining, as a result of being cured, a highly reliable cured product (molded article) exhibiting excellent heat resistance and mechanical strength. This thermosetting resin composition includes: a polyalkenyl phenol resin (A); an aromatic polymaleimide compound (B); and a polymerization initiator (C). The polyalkenyl phenol resin (A) has, in a molecule thereof, at least one aromatic ring unit (al) which has a phenolic hydroxyl group having a 2-alkenyl group bonded thereto, and at least one aromatic ring unit (a2) having a phenolic hydroxyl group which does not have a 2-alkenyl group bonded thereto. Each of the aromatic ring units is bonded by a linking group having a main chain which is not formed by an aromatic ring. When m represents the number of the aromatic ring units (a1), and n represents the number of the aromatic ring units (a2), the ratio of m to (m+n) is 40-90%. The polyalkenyl phenol resin (A) is included in an amount at which the amount of 2-alkenyl groups becomes 0.4-1.5 mol per mol of maleimide groups in the aromatic polymaleimide compound (B).

    Abstract: A method for producing metal nanowire of small diameter and long length. In the method for producing a metal nanowire, a first solution containing an ionic derivative and a polyol as a solvent are kept at 80-200° C., and a second solution containing a metal salt and a polyol as a solvent is supplied into the first solution so that the ratio between the number of moles of metal atoms in the metal salt supplied in one minute and the total number of moles of halogen atoms in the ionic derivative in the first solution (the number of moles of metal atoms in the metal salt supplied in one minute/the total number of moles of halogen atoms in the ionic derivative) is less than 10. It is preferable that the ionic derivative is a quaternary ammonium halide and the metal salt is silver nitrate.
