A suspension coil spring includes a lower end turn portion (42), an upper end turn portion (44), and a helical effective portion (45) formed between the end turn portions (42, 44). The lower end turn portion (42) includes a first portion (42a) which contacts a lower spring seat irrespective of a load, and a second portion (42b) which contacts the lower spring seat or is separated from the same according to the load. The wire diameter of the second portion (42b) is greater than that of the first portion (42a) and an average wire diameter of the effective portion (45). The upper end turn portion (44) includes a third portion (44a) which contacts an upper spring seat irrespective of a load, and a fourth portion (44b) which contacts the upper spring seat or is separated from the same according to the load. The wire diameter of the fourth portion (44b) is greater that of the third portion (44a) and the average wire diameter of the effective portion (45).
