A thickness meter detects a thickness of an electrode plate of a secondary battery at three or more points in a width direction of the electrode plate. A calculator calculates three feature amounts of a first deviation between the thickness target value and a thickness measurement value of a point closest to a first compression mechanism among the three or more points, a second deviation between the thickness target value and a thickness measurement value of a point closest to a second compression mechanism among the three or more points, and a secondary component of a thickness profile of the electrode plate from thickness measurement values at the three or more points and the thickness target value, and adaptively changes the setting values of the first compression mechanism, the second compression mechanism, a first bend mechanism, and a second bend mechanism on the basis of the three feature amounts.

Provided is a lithium secondary battery comprising: a positive electrode including a positive electrode active material; a negative electrode including a negative electrode active material; and a first functional layer between the positive electrode and the negative electrode, wherein the first functional layer includes plate-like polyolefin particles having an average diameter of 1 μm to 8 μm, and the positive electrode includes a positive electrode active material layer including a positive electrode active material and a flame retardant, or has a stacked structure including a positive electrode active material layer and a second functional layer including a flame retardant.

Provided are a solar cell and a light emitting device with low leakage current and low cost, using ZnO fine particles. A p-type ZnO layer (p-type layer) (14) made primarily of p-type ZnO fine particles (931) is formed. P-side electrodes (16) are formed at a plurality of regions on the p-type layer (14). A thin insulating layer (18) is formed between an n-type layer (13) and the p-type layer (14). In the insulating layer (18), openings are formed at regions A each not overlapping the p-side electrodes (16) and being apart from them in a plan view. In the configuration, by thus making the p-side electrodes (16) apart from the regions A, the length of a current path in the p-type layer (14) can be made substantially larger than the layer thickness. Accordingly, even when n-type ZnO fine particles (932) are incorporated in the p-type layer (14), it is possible to interpose some of the p-type ZnO fine particles (931) along a leakage current path caused by the incorporation, and thereby cut off the current path.
