To provide a mobile terminal having a board support structure capable of reducing impact on built-in components of the mobile terminal when a housing thereof undergoes a primary mode of deformation.The upper end portion and the lower end portion of a main board 40 are supported by bosses 111a, 111b, 113a, and 113b. The upper end portion and the lower end portion of the main board 40 are fixed in a direction perpendicular to the surface of the main board 40. The upper end portion thereof slides with respect to the peripheries of small-diameter cylindrical portion insertion holes 211a and 211b of a module holding board 30 on the front side and a rear housing 20 on the rear side. Thus, the main board 40 can move in a plane direction (in a longitudinal direction).
