Patent ID: 7527668

Claim:
A method for manufacturing metal fine particles, the method comprising the steps of using an aqueous solution containing an amine having a reducing capacity and an ammonium salt having substantially no reducing capacity so as to reduce metal ions with said amine in a presence of said ammonium salt, thereby manufacturing rod-shaped metal fine particles, wherein at least one selected from alkylamines and alkanolamines represented by formula (2) to (5) shown below is used as said amine: NR 3 (R: C n H 2n+1 n=an integer from 1 to 8) Formula (2); N(ROH) 3 (R: C n H 2n n=an integer from 1 to 8) Formula (3); H 2 NR (R: C n H 2n+1 n=an integer from 1 to 8) Formula (4); and HNR 2 (R: C n H 2n+1 n=an integer from 1 to 8) Formula (5).
