<P>PROBLEM TO BE SOLVED: To provide a multi-core writing utensil which increases the degree of freedom on design of a lid while being able to acquire the smart appearance of a rear end part easily. <P>SOLUTION: Each operation section 6 is made to be projected from each window hole 41 of a barrel 2, and an opening 42 capable of being opened and closed while opening the window hole 41 backward is formed in the rear end of the barrel 2. The writing utensil and the operation sections 6 are composed so as to be detached from the inside of the barrel 2 and inserted into the barrel 2 through the opening 42. The lid 5 enabling the opening 42 to be opened and closed freely is formed in the rear end of the barrel 2. One end of the lid 5 is connected with the rear-end side wall of the barrel 2 by a hinge part 45 so as to be rotated freely, and the lid 5 rotates in the nearly back and forth direction when the opening 42 is opened and closed. An engaging projection 53 with which a finger engages when pressing the lid 5 backward in order to open the opening 42 is formed in another end of the lid 5.
