Abstract
A light-emitting module includes a substrate, and elongated light-emitting units arranged in rows on the substrate. Each light-emitting unit includes an element array of light-emitting elements arranged on the substrate and a sealing member sealing the element array. The sealing member contains a wavelength converting material. When the light-emitting units are viewed from a direction that is parallel to a surface on which the plurality of light-emitting units are arranged and coincides with a row direction being a direction along which the light-emitting units are arranged in rows, two of the light-emitting units are arranged such that portions of one of the two light-emitting units nearer to the center in the row direction are visible without being obstructed by the other light-emitting unit.
