To provide a method for assembling line post(LP) insulators which can be easily assembled without using a box and can be applied to various lengths of products and an assembled body of LP insulators in which packaging material to be used are small in number and light in weight and the amount of wastes after the insulators are unpacked is small and the insulators can be lifted easily.

The integrated body of LP insulators consists of LP insulators 2 each mainly composed of an axial body 3, a locking member 4 and a supporter 5, a pallet 9 in which a mount surface is formed by placing flat boards across interval holding members 7 to erect thereon LP insulators 2, fixing members 10 to fix the supporter 5 to the pallet 9, and a bundling member 12 to bundle the members 4 together. In this case, the mount surface of the pallet 9 and the supporter 5 are fixed by the members 10 to erect a plurality of the insulators 2 and the members 4 are bundled together.
