A transparent silicone pressure-sensitive adhesive composition that exhibits excellent antistatic performance, is able to maintain that excellent antistatic performance even when exposed to high temperatures for a long time, and suffers no deterioration in adhesive properties, as well as a silicone pressure-sensitive adhesive tape that uses the composition. The composition comprises: (A) a straight-chain diorganopolysiloxane, (B) a polyorganosiloxane comprising R

SiO
0.5
units and SiO
2
units, in which the molar ratio of R

units is within a range from 0.6 to 1.7 (wherein R
1
represents a monovalent hydrocarbon group of 1 to 10 carbon atoms), and (C) an ion-conductive antistatic agent, wherein the quantity of the ion-conductive antistatic agent of the component (C) is within a range from 0.01 to 5 parts by mass per 100 parts by mass of a combination of the straight-chain diorganopolysiloxane of the component (A) and the polyorganosiloxane of the component (B).
