In a method of producing a microgripper including a grip finger 100 which has a coupling portion 100g that commonly owns one ends of three V-shaped edges 100v on an open end side, other ends of the V-shaped edges 100v being connected to a case 14, and in which the coupling portion 100g is connected to a moving portion of a translational driving section 12, and the coupling portion 100g is pulled on the basis of translational movement, whereby displacement amounts of the tip ends of the V-shaped edges 100v are inwardly magnified more than an amount of the translational movement, the method comprises the steps of: in a state where the grip finger 100 has three edge portions 101a in which the V-shaped edges 100v having the coupling portion 100g are developed in a substantially flat plane, outwardly bending the edge portions 101a at a substantially center; and inwardly bending the edge portions 101a at a vicinity of the coupling portion 100g.
