A linear motor armature in which pressure loss of a coolant flowing in a cooling conduit and possible significant non-uniformity in temperature distribution are reduced over the entire armature. A manifold 5, 6h and a pair of cooling conduits 7, 9 are configured such that a coolant is supplied from one connecting conduit 27 of the cooling conduit 7, and one connecting conduit 33 of the cooling conduit 9, and discharged from the other connecting conduit 29 of the cooling conduit 7 and the other connecting conduit 35 of the cooling conduit 9.
