PURPOSE: To obtain a method for producing a drum core with pins with prevention of occaurence of a defective and enhancement of a productivity. CONSTITUTION: In a pin connecting body 5, a plurality of inverted J-shaped resiliently deforming parts 5d are attached to a base plate 5c, and a collapsed part 5e is formed on a top of each of the resiliently deforming parts 5d so as to be spaced a distance L1 from the base plate 5c smaller than a height L2 of a drum core 1. The drum core 1 is fitted to the pin connecting body 5 by inserting the collapsed parts 5e of the pin connecting body 5 into pin holes 1b of the drum core 1. An adhesive is poured into the pin holes 1b of the drum core 1 and cured for a predetermined time. After that, the pin connecting body 5 is cut at a predetermined cutting line, and an unwanted part is removed. In this manner, the pin connecting body 5 is temporarily held by its resiliently restoring force. In this state, the adhesive is cured.
