A non-aqueous electrolyte secondary battery uses, as its positive electrode or negative electrode, an electrode containing an active material and a conductive agent, the active material being made of a mixture of a molybdenum dioxide and a lithium titanium oxide in a weight ratio (molybdenum dioxide: lithium titanium oxide) of from 90:10 to 50:50, and the conductive agent containing graphitized vapor grown carbon fiber and massive graphite. The massive graphite has an average particle size of 10 &#x3bc;m or greater.

A printed circuit board with a coin type electric element of the present invention has the coin type electric element, and printed circuit board, on which the coin type electric element is fixed by soldering. The coin type electric element have a coin exterior case formed of metal and in a coin shape with an opening; a sealing plate, which is fixed on the opening of the coin exterior case, sealing the coin exterior case; and an insulating seal interposed between the coin exterior case and the sealing plate. The coin exterior case and the sealing plate are composed of a pair of terminals, A lead, whose tip portion is bent toward a surface side of a first terminal face, is connected to a second terminal face of the coin type electric element. A soldering face to be soldered by reflow soldering is provided at the tip portion.
