The invention discloses a capacitor guide pin and a manufacturing method thereof. The capacitor guide pin is composed of an aluminum wire and a tin-plated copper-clad steel wire. A part of the aluminum wire is punched to form a flat head, and another part of the aluminum wire is a cylinder located at the transverse center line of the flat head. A transitional portion is formed between the flat head and the cylinder and is in a square R shape. The flat head is an arc structure. The tin-plated copper-clad steel wire and the cylinder of the aluminum wire are soldered and have a solder joint therebetween in a truncated cone shape. The front end surface of the tin-plated copper-clad steel wire is a circular arc end face, and has a radius of a half of the diameter of the tin-plated copper-clad steel wire. The transitional portion is in a square R shape and has large bending strength so as to avoid damage and fracture during the assembly of a container. The flat head is an arc structure so asto reduce the probability of piercing the inner foil and improve product quality. The size and the appearance of the solder joint can be well controlled to avoid puncturing the rubber in the apertureor exposure after a rubber plug is inserted.
