Room-temperature-curable silicone composition and electric/electronic apparatus

A room-temperature-curable silicone composition comprising:

• (A) 100 parts by mass of an organopolysiloxane represented by the following general formula:
• wherein each R1 is the same or different monovalent hydrocarbon group lacking an aliphatic unsaturated bond, each X is an alkoxysilyl-containing group represented by the following general formula:
• wherein each R1 is as defined above, R2 is an alkyl group, each R3 is the same or different alkylene group, “a” is an integer from 0 to 2, and “n” is an integer from 1 to 20, and “m” is an integer from 50 to 1000;
• (B) 50 to 200 parts by mass of an organopolysiloxane resin represented by the following average unit formula:
• (R43SiO1/2)b(R42SiO2/2)c(R4SiO3/2)d(SiO4/2)e
• wherein each R4 is the same or different monovalent hydrocarbon group, however, not more than 5 mol % of R4 in a molecule are aryl groups, and “b”, “c”, “d” and “e” are numbers satisfying the following conditions:
• 0≤b<0.2, 0.1≤c≤0.5, 0.4<d≤0.9, 0≤e<0.2, and b+c+d+e=1;
• (C) 0.5 to 20 parts by mass of an alkoxysilane represented by the following general formula:
