In an electrical component socket, an electrical component can be removed easily even if a fixed contact potion bites into an electrical component terminal. In the electrical component socket (11), a floating plate (14) to accommodate an IC package (12) is provided in a socket body to be able to move up and down, and is biased upward by a biasing member. In a movable contact piece (15b) of a contact pin (15), a pressing projecting piece (15m) is formed. In the floating plate (14), a pressed part (14m) to be pressed by the pressing projecting piece (15m) is formed. When the movable contact piece (15b) is elastically deformed in an opening direction and a movable contact part (15g) separates from an IC lead (12b), the floating plate (14) rises upward by the biasing member, and the IC lead (12b) separates from a fixed contact part (15d).
