Method of producing a movable part of a wire-dot print head
 In a method of producing a movable part of a wire-dot print head comprising an armature supported by a plate spring, and a lever having a tip to which print wire is fixed, the armature and the lever are formed of alloys containing identical atoms or alloys easy to diffuse into each other, a bond part of a base part of the lever is inserted in a bond groove in a tip of the armature, and the lever and the armature are heat-treated in vacuum at a temperature not lower than 1100.degree. C. and below the melting points of the lever and the armature, so that the lever and the armature are diffusion-bonded.
