PROBLEM TO BE SOLVED: To provide a formation method of a joint part by which the joint part excellent in acid resistance, water shielding property, etc. can be easily formed in a short time with good finish, and to provide powder for filling the joint part by which the joint part can be filled easily, and heating and melting can be quickly carried out. SOLUTION: The formation method of the joint part includes a process for filling the powder of the particle size of 5 mm or less including modified sulfur and an inorganic fine aggregate in the joint part, a process for heating the powder filled in the joint part and melting the modified sulfur, and a process for cooling and solidifying the melted modified sulfur. The powder for filling the joint part is composed of a pulverized material of a solidified material including the modified sulfur pulverized to the particle size of 5 mm or less, of which the solidified material including the modified sulfur is obtained by cooling and solidifying the mixture of a melted material of the modified sulfur and a melted inorganic fine aggregate of a specified particle size, or is composed of the mixed powder including the modified sulfur powder of the particle size of 5 mm or less and the inorganic fine aggregate of the specified particle size, which are mixed by the mass ratio of 1:0.5 to 10.
