PROBLEM TO BE SOLVED: To bend a writing body of a multi-core writing instrument in the shaft-radial direction toward the shaft axis of a shaft cylinder of a slide member into a desired bending angle, in a slide member connected with the writing body by inserting under pressure a connecting part provided at a tip of the writing body into the opened rear end in the writing body as a constituent element of a delivering means for retracting the writing tip of the writing body through the opening of the tapered shaft cylinder tip. SOLUTION: The connecting part 21 of the slide member 12 is connected to the writing body 8 while being bent. The tip end face 19a of the tip 19 of the slide member with the connecting part is projected to the front of the connecting part side from both ends in the shaft-radial direction of the center, in the shaft-radial direction toward the shaft axis of the shaft cylinder, into a ridge-shape 23 having the same projection amount in the direction orthogonal to the shaft-radial direction. When the connecting part of the slide member is inserted under pressure into the rear end 20 of the writing body, the writing body is bent to the slide member, the rear end of the writing body is abutted on the slope of the ridge shape of the tip of the slide member.
