A glass particle deposited body manufacturing method for manufacturing a glass particle deposited body, in which a plurality of glass particle synthesizing burners are arranged at regular intervals to be opposed to a rotating starting rod, comprising the steps of: relatively reciprocating said starting rod and said glass particle synthesizing burners in parallel in such a manner that a turn-back location from a homeward path to an outward path of reciprocating movement does not go beyond the initial position to move the turn-back location from the outward path to the homeward path of reciprocating movement in a certain direction, and move said turn-back location from the homeward path to the outward path of reciprocating movement in the reverse direction if said turn-back location from the outward path to the homeward path of reciprocating movement is moved to a predetermined position, until each burner is returned to an initial position, which operation is defined as one set of operation, sequentially these operations being repeated so that glass particles synthesized by burners are deposited sequentially on a surface of the starting rod, with reciprocating movement of the outward path of (B+1)xA and the homeward path of BxA, (A: movement distance at once of the turn-back location, B: integer (1,2,3,...)), and reciprocating movement of the outward path of (B+1)xA and the homeward path of (B+2)xA in reverse direction after the turn-back location moves to the predetermined position, characterized in that an average reciprocating movement distance D=2x(B+1)xA of said one set is less than double a burner-to-burner interval, and by setting the number of deposited layers on a stationary portion to be uniform along a length direction at the time when each burner of said one set returns to the initial position. relatively reciprocating said starting rod and said glass particle synthesizing burners in parallel in such a manner that a turn-back location from a homeward path to an outward path of reciprocating movement does not go beyond the initial position to move the turn-back location from the outward path to the homeward path of reciprocating movement in a certain direction, and move said turn-back location from the homeward path to the outward path of reciprocating movement in the reverse direction if said turn-back location from the outward path to the homeward path of reciprocating movement is moved to a predetermined position, until each burner is returned to an initial position, which operation is defined as one set of operation, sequentially these operations being repeated so that glass particles synthesized by burners are deposited sequentially on a surface of the starting rod, with reciprocating movement of the outward path of (B+1)xA and the homeward path of BxA, (A: movement distance at once of the turn-back location, B: integer (1,2,3,...)), and reciprocating movement of the outward path of (B+1)xA and the homeward path of (B+2)xA in reverse direction after the turn-back location moves to the predetermined position, characterized in that an average reciprocating movement distance D=2x(B+1)xA of said one set is less than double a burner-to-burner interval, and by setting the number of deposited layers on a stationary portion to be uniform along a length direction at the time when each burner of said one set returns to the initial position.
