PURPOSE: To provide a key switch and its manufacturing method that can contrive the promotion of miniaturization and the enhancement of assembling work efficiency by making a cross-linked body by simply and surely connecting a pair of lever members without depending on a manual work. CONSTITUTION: It includes making a pair of lever members 3, 4 constituting a cross-linked body 10 into a shaping article consisted of resin materials whose shrinking rate is different each other and arranging an axis inserting aperture 4d into one side of lever member 4 consisted of resin material 13 having a small shrinking rate along with arranging a connection axis 3d into the other side of lever member 3 consisted of a resin material 15 having a large shrinking rate. With this, after shaping the one side of lever member 4 having the axis inserting aperture 4d, since it can attach the connection axis 3d to the axis inserting aperture 4d by shaping the other side of lever member 3 by solidifying the resin material 15 having a large shrinking rate within a metal mold in which the axis inserting aperture 4d is a portion of cavity, it is not necessary to connect both lever members 3, 4 with a manual work.
