PURPOSE: To make it possible to weld a chip piece on a lead frame in a state that the chip piece is reliably positioned on the lead frame and to make it possible to realize an increase in the capacitance of a solid electrolytic capacitor.

CONSTITUTION: A solid electrolytic capacitor manufacturing device of a structure, wherein a capacitor element, which has a chip piece 2 and an anode terminal 1 made to project from the piece 2, is made to transfer on a lead frame 5 having one pair of lead terminals extendedly provided at a prescribed interval and the terminal 1 is connected with the lead terminal on one side of the lend terminals, is provided with position correcting means 9 and 8 which make the positions, which are positioned in the lengthwise and width directions of the lead frame, of the chip piece on the lead frame correct.
