Abstract:
1. An image reading apparatus comprising: a light source that irradiates a document with light, the light source comprising: a Multilayer substrate; and a plurality of light emitting elements linearly arranged on a first surface of the multilayer substrate; a light receiver that receives reflected light reflected from the document, and metal films formed between single layer substrates included in the multilayer substrate and extending in a direction perpendicular to a direction of the at least a pair of through holes, wherein the multilayer substrate comprises at least a pair of through holes each having an inner surface on which a reinforcement member is disposed, the at least a pair of through holes being formed so that one of the light emitting elements is interposed therebetween, wherein each of the reinforcement members contacts a wiring formed on the first surface of the multilayer substrate and another wiring formed on a second surface of the multilayer substrate opposite the first surface, and wherein an entity of the one of the light emitting elements is interposed between the at least a pair of through holes, and wherein the metal films formed between the single layer substrates and the reinforcement members formed on the inner surfaces of the through holes contact each other.
