There is provided an input apparatus for game systems, which are simplified in construction. The input apparatus has a base (21) having a plurality of panel-attaching sections (26), a plurality of foot panels (50) arranged respectively at a plurality of panel-attaching sections (26), and tape switches (30) not only arranged between a panel supporting surface (27a) formed on each of a plurality of panel-attaching sections (26) and each of the foot panels but also outputting a predetermined detection signal responsively to changes in pushing load onto each foot panel (50). The tape switch (30) has a sensing element (31) and an elastic-material-made coating member (32) covering the sensing element (31) and functioning as a medium transmitting a load applied to each foot panel 50 to the sensing element (31). The coating element (32) supports the foot panel (50) by contacting with each foot panel (50). Ribs (32a, 32b) are formed on the coating member (32), so that a load is intensively transmitted to a desired position on the sensing element (31).
