A light guide for a virtual image device to guide and emit image light output from an image display element to display a virtual image. The light guide includes a light-guide member and an optical member. The light-guide member includes an incidence portion to receive the image light and an exit portion to emit the image light to an outside, and a reflective portion inclined relative to the incidence portion to guide the image light received by the incidence portion into the light guide. The light-guide member also includes an extraction portion including first planes each inclined relative to the exit portion and second planes each parallel with the exit portion, to guide the image light from each first plane to the exit portion and extract the image light. The optical member includes a parallel plane and an inclined portion.

Terminal pads are arranged on a first surface of the substrate for an electronic component to receive terminals of the electronic component. An electrically-conductive film is formed on a second surface defined on the back of the first surface over the back of a mounting area for the electronic component. The mounting area is contoured along the outer periphery of the arrangement of the terminal pads. The ratio of the area of the electrically-conductive material to the area of the surface of the substrate over the back of the mounting area is set appropriate to the ratio of the area of the electrically-conductive material to the area of the surface of the substrate over the mounting area for each electronic component. This results in suppression of flexure of the printed wiring board during reflow.
