Abstract: Provided is a resin foam (13) that highly restrains the occurrence of display irregularities in a display unit when the resin foam is used in a touch-screen-equipped device (1), where the display irregularities may occur with user's touch operations. The resin foam (13) according to the present invention is obtained by expansion of a resin composition including a resin. The resin foam has a 25% compression load of 0.1 N/cm2 to 8.0 N/cm2 and is used in the touch-screen-equipped device (1). The resin is preferably at least one resin selected from the group consisting of polyolefin resins, polyester resins, and acrylic resins.
