Abstract: Provided is a resin composite having high mechanical properties which make the resin composite moldable into and usable as members for use in applications such as vehicle-mounted members and electrical materials. The resin composite comprises 0.5-40 mass % chemically modified, fine cellulose fibers and a resin, wherein the chemically modified, fine cellulose fibers have a pyrolysis initiation temperature (TD) of 270° C. or higher, a number-average fiber diameter of 10 nm or larger but less than 1 ?m, and a degree of crystallinity of 60% or higher. In a preferred embodiment, the chemically modified, fine cellulose fibers have a coefficient of variation (CV) in DS unevenness ratio, DSs/DSt, of 50% or less, the DS unevenness ratio being the ratio of the modification degree (DSs) of the surface layers of the fibers to the modification degree (DSt) of the whole of the fibers.

Abstract: An illuminated push button unit includes a light-guide lens, a lens holder and a push-down control. The light-guide lens is configured to guide light from a light source to a light emission face disposed at a front end of the light-guide lens and emit the light from the light emission face. The lens holder is attached to the light-guide lens. The lens holder includes a light emission window through which the light emission face of the light-guide lens emits the light. The push-down control is attached to the light emission face in a middle of the light emission face so that the light emission face emits the light in an annular shape.
