PROBLEM TO BE SOLVED: To provide a container lid of synthetic resin which is capable of suppressing displacement of a body in the circumferential direction to a tamper-evident skirt section without any trouble when the elevating distance of the body is long during the detachment of the body, avoiding breakage of a non-breakable connecting piece when opening a neck portion, and avoiding breakage of a breakable bridging portion when attaching the container lid to the neck portion. SOLUTION: A container lid opening neck has the non-breakable connecting piece at the tamper-evident skirt section, wherein the container lid includes the tamper-evident skirt section 6 connected to the body 4 via breakable bridge sections arranged with a spacing from the body in the circumferential direction, and the container lid is configured such that, even if the bridge sections are broken and the body is separated from the opening neck of the container, the container lid is kept mounted to the opening neck of the container. The non-breakable connecting pieces include two tilting portions 54a, 54b, 58a, and 58b tilting opposite to each other, respectively. Guide pieces 48a and 48b projecting upwardly between the projecting piece 46 and the non-breakable connecting piece, and brought close to both side edges of the projecting piece, are arranged on the tamper-evident skirt portion.
