An apparatus for manufacturing an element array includes a substrate hold means, a laser radiation device, and a collection mechanism. The substrate hold means holds a substrate including an adhesive layer on which elements are attached in a predetermined array while a surface of the adhesive layer is inclined relative to a horizontal surface at a predetermined angle. The laser radiation device radiates a laser to a specific element among the elements attached on the adhesive layer. The collection mechanism is disposed below the substrate and configured to receive the specific element falling by the laser radiation.

In a method of manufacturing an element array, prepared is an adhesive sheet in which elements are arranged in a predetermined array on an adhesive layer. A specific element among the arrayed elements is removed from the adhesive sheet by radiating a laser to the specific element. The arrayed elements are directly or indirectly transferred onto a mounting substrate.
