PROBLEM TO BE SOLVED: To make large bubbles and improve the rate of making bubbles significantly by forming a bugle-shaped tube part, made of a see-through material, of a bubble making instrument or by forming an arc-shaped inner rim part at a rim part of an end of a large opening of the tube part. SOLUTION: A large-sized bubble can be made by providing a bugle-shaped tube 2 expanding toward the end and communicating with the other end of a blowing tube 1 with a blowing opening 1a at one end and by bending to form the arc-shaped inner rim part 2d expanding toward the end at the rim part 2c of the end of the large opening to make a small bubble touch internally to the rim part 2c smoothly. The rate of making bubbles can be increased since the bugle-shaped tube 2 made of a see-through material allows a user to blow air from the blowing opening 1a before a film F of a bubble solution generated inside the bugle-shaped tube 2 and moving to the side of the blowing tube 1 with the decreasing diameter disappears.
