A method for producing a drawn glass member includes a step of thermally softening and drawing a first end of a first glass base material, and a step of thermally bonding together a second end of the first glass base material, having the first end thermally softened and drawn, with one end of a second glass base material to form a thermally bonded portion. The step of thermally bonding together the second end of the first glass base material with the one end of the second glass base material is executed, while pressing, along a direction of the drawing, a side plane of at least one of the first and second glass base materials including the thermally bonding portion so as to keep a cross-sectional shape of at least one of the first and second glass base materials.
