Abstract

An electro-optical device includes a cable connected to an electronic component, a storage casing that stores the electronic component and an optical component and has an insertion hole through which the cable is inserted, a fixing portion that is fixed to the storage casing, and an elastic portion that is fixed to the fixing portion. The fixing portion has a first opposing portion and a second opposing portion that are disposed opposite to each other with the cable that protrudes from the insertion hole, interposed therebetween, and the elastic portion includes a first protruding portion and a second protruding portion, and the first protruding portion and the second protruding portion are pressed against each other with the cable interposed therebetween and are disposed so as to surround a vicinity of the cable.
