PROBLEM TO BE SOLVED: To provide an improved strong cushion rubber by reinforcing a most easily broken position on infinitely stretching the cushion rubber in a fishing cushion rubber or in another member. SOLUTION: This cushion rubber C positioned in between a main line A and leader B and consisting of a linear elastic material 1 is provided by making a terminal connection structure of the elastic linear material 1 linked with a linking part 4 by melt-bonding for overlapping a loop body 2 which is a terminal part of the linear elastic material 1 and linked with the linking part 4 of a swivel 3, with an individual second loop body 5 resembling with the loop body 2. Also the terminal connection structure is provided by nipping a packing 6 at the melt-bonded part 1a where both of the root parts 5a of the loop body 2 installed at the terminal part of the linear elastic material 1 and the second loop body 5 overlapping to it overlap and then high frequency melt-bonding both of them.
