A switching power supply includes a switching element, a constant current element, a rectifying element, a first inductor, a second inductor, and a control circuit. If the switching element is on, the switching element supplies a power supply voltage to the first inductor and feeds an electric current. The constant current element turns off the switching element if the electric current of the switching element exceeds a predetermined upper limit. The rectifying element feeds the electric current of the first inductor if the switching element is turned off. The second inductor supplies the induced potential to a control terminal of the switching element. The control circuit supplies a pulse-like potential to a control terminal of the constant current element and outputs if an average of the potential is lower than a lower limit.

Disclosed is a functional laminated sheet having flexibility, high body and good die cutting workability. The functional laminated sheet comprises a laminated sheet composed of at least two plastic films bound to each other through an adhesive layer and a functional layer formed on one surface or both surfaces of at least one of the plastic films, wherein the adhesive layer has a Martens hardness of 260 N/mm2 or less. The functional layer is, for example, a layer having an electromagnetic wave shielding function, a heat ray reflection function, a gas barrier function or a planar heat generation function, and can be arranged in the inside of the laminated sheet. Alternatively, the functional layer is a layer having a light reflection function, a light permeation control function or an antifogging function, and can be arranged on the outermost surface of the laminated sheet. Also disclosed is a transparent electrically conductive laminated sheet for a touch panel, which comprises a transparent laminated sheet having a transparent plastic film bonded thereto through the adhesive layer and a transparent electrically conductive layer formed on the transparent laminated sheet.

According to one embodiment of the invention, there is provided a switching power supply device including a rectifying circuit and a switching operation conversion circuit. The rectifying circuit receives a phase-controlled alternating voltage to rectify to a direct voltage. The switching operation conversion circuit starts up by being applied with the direct voltage, and includes a normally on type switching element and an off driving circuit. The normally on type switching element passes an input current, and the off driving circuit turns off the switching element when the input current reaches a prescribed value. The switching operation conversion circuit converts the direct voltage to an output voltage different from the direct voltage by repeating a switching operation of turning on and off the switching element.
