A multi-shaft linear motor formed by a plurality of linear motors each provided with a magnetic body and an armature and adapted to produce a force causing the magnetic body and the armature to be relatively displaced along a given linear moving direction by interaction of magnetic fluxes generated between the magnetic body and the armature during an operation of supplying electric power to the armature. Each of the single-shaft linear motors includes a base plate. Base plate has a base surface defining the moving direction, wherein the stator is fixed onto the base surface along the moving direction, and the mover is attached onto the base surface in a movable manner reciprocating along the moving direction and in opposed relation to the stator. Single-shaft linear motors are stacked in a stacking direction perpendicular to the base surface such that the single-shaft linear motors are individually detachable as a unit.
