Abstract: According to one embodiment, a component supporting device includes a cover having a through-hole, a support covered with the cover, a component arranged between the cover and the support, and a fixing tool which is inserted into the through-hole of the cover from an outside of the cover and sandwiches the component between the support and the fixing tool. The fixing tool includes an elastically deformable main body having an apical surface to butt to the component, a hook provided on the main body to engage with an edge of the through-hole inside the cover, and an operating portion provided on the main body to protrude from the through-hole outside the cover which is configured to release the engagement of the hook with the edge of the through-hole through elastic deformation of the main body.
