Fiber bundle joining apparatus and fiber bundle joining method

A fiber bundle joining apparatus comprising:

• a support table configured to hold a terminal end portion side of a first fiber bundle impregnated with resin;
• a roller mechanism having a roller around which a leading end portion side of a second fiber bundle impregnated with resin is able to be wound;
• a movement mechanism configured to perform a first movement for moving the roller mechanism that is in a state where the leading end portion side of the second fiber bundle is wound around the roller, to a vicinity of the terminal end portion side of the first fiber bundle held on the support table, and a second movement for further moving the roller mechanism on the terminal end portion side of the first fiber bundle after the first movement to create a state where the leading end portion side of the second fiber bundle is stacked on the terminal end portion side of the first fiber bundle;
• and
• a thermocompression bonding mechanism configured to integrally pressure-bond the terminal end portion side of the first fiber bundle and the leading end portion side of the second fiber bundle stacked on the support table.
