An electronic apparatus includes an upper case and a lower case. An end face of the upper case includes a first upper step surface and a second upper step surface located at high and inner positions with respect to the first upper step surface. An end face of the lower case includes a first lower step surface, a second lower step surface located at high and inner positions with respect to the first lower step surface, and a third lower step surface located at high and inner positions with respect to the second lower step surface. The first upper step surface is located at a low position with respect to the second lower step surface and faces the first lower step surface. The second upper step surface is located at a low position with respect to the third lower step surface and faces the second lower step surface.
