摘要： The present invention provides a joining structure with a joining strength higher than that of a conventional rubber core cord joining structure of a rubber ring. The invention also provides a solidifying agent for joining a rubber core cord that provides such a joining structure. A joining structure 2 of a rubber core cord 11 according to the present invention is a rubber core cord joining structure of which opposite end portions of the rubber core cord 11 or end portions of two rubber core cords are joined to each other with an adhesive. A solidified portion 23 formed by a solidifying agent 25 that has solidified is formed at each of the opposite end portions of the rubber core cord 11 or each of the end portions of the two rubber core cords, and the solidified portion 23 contains porous particles. The solidifying agent 25 according to the present invention is a solidifying agent that is applied to the rubber core cord 11, and contains a solvent containing a solidification component and porous particles contained in the solvent.
