The membrane touch panel is gradually becoming more popular and it is necessary that the optimum design based on theoretical analysis is used for developing the high reliable touch panel. In this paper, the touch force needed for the sheets of membrane touch panel to come into contact with a finger, P_0,is analyzed theoretically using the model of continuous plate which is supported by array of dot spacers placed at a pitch, and which is uniformly loaded. As a result, it is shown that the numerical solutions calculated by the deflection equation of the continuous plate model approximately agree with the experimental results. It is also clarified that the touch force P_0 depends on the ratio of spacer height to sheet thickness, h/t, the ratio of sheet thickness squared to spacer pitch, t^2/a, the ratio of loaded area to spacer pitch and the spacer pitch ratio, and that the touch force P_0 is in direct proportion to both h/t and (t^2/a)^2. Also, a process of optimum design is suggested.
