A method for manufacturing sealing tool comprising a socket (3) and a head (4) at one end and the other end of a linear element (2) respectively and a protrusion (11) for locking the head (4) in a head-insertion hole (10) of the socket (3), which comprises the steps in the mentioned sequence of fixing a core ball (13) and either the socket (3) or the head (4) to the linear element (2), cutting the linear element (2) at a point close to the core ball (13), pulling the linear element (2) to bring the core ball (13) to be set in a cavity (27) and filing a synthetic resin in the cavity (27) in a manner such that the core ball (13) and the socket (3) engageable with the head (4) are integrally formed.
