Abstract

A curable organopolysiloxane composition having rheological properties suitable for precision application and fine pattern formation by a fine droplet coating apparatus such as a jet dispenser, along with a method for forming a pattern using the same, and an electronic component using the same, is provided herein. The curable organopolysiloxane composition is hydrosilylation reaction curable and can be precisely applied by a jet dispenser, etc. The composition has a viscosity at a strain speed of 1,000 (1/s) of 2.0 Pa·s or less, while the viscosity at a strain speed of 0.1 (1/s) is a value 50.0-fold or more the viscosity at a strain speed of 1,000 (1/s). The content of silicon atom-bonded aromatic functional groups in the composition is within a range of from 1.0 to 6.0 mass %.
