PROBLEM TO BE SOLVED: To provide a method and a device for forming a abrasive wheel which can be applied to highly accurate optical element machining without uniform forming marks in the rotational direction of the abrasive wheel. SOLUTION: The method for forming an abrasive wheel is used for forming an annular abrasive wheel (8) by rotating the annular abrasive wheel (8) used for aspheric surface grinding and a straight cup abrasive wheel (4) on the forming device (1). The straight cup abrasive wheel (4) can be rotationally driven around a first rotary shaft (a Z-axis) so that the forming face of the straight cup abrasive wheel (4) comes into contact with the annular abrasive wheel (8) on both ends of its diameter. The annular abrasive wheel (8) can be rotationally driven around a second rotary shaft (an X-axis) crossing with the first rotary shaft (the Z-axis). The annular abrasive wheel (8) can be formed by executing movement control for relatively moving the straight cup abrasive wheel (4) and the annular abrasive wheel (8) at least in the direction of approaching/separating from each other, in the mutually crossing direction, and in the direction (a B-axis) of changing an angle of the second rotary shaft (the X-axis) of the annular abrasive wheel (8) to the straight cup abrasive wheel (4).
