PURPOSE:To obtain an organic solvent cell with good workability, small internal resistance, and excellent heavy load discharge performance by forming uneven parts on the inner surface of a negative electrode sealing plate, making metal particles adhere to them, and press-fitting the negative electrode to them. CONSTITUTION:A number of uneven parts 7 are formed by spraying particles such as Ni-Cr steel, etc. on the inner surface which is adjacent to the negative electrode 3 of a sealing plate 4 that is served additionally as a negative electrode terminal by the sand blast treatment at high speed and the particle 8 of the Ni-Cr steel is made to adhere firmly. When the negative electrode 3 such as metal lithium is press-fit to this sealing plate 4, the projection of the adhered particle 8 reaches the inner part of the negative electrode 3 and the contact area is expanded by the uneven parts 7. As a result, an excellent collection effect can be obtained. |
