    摘要： An electrochemical cell of improved anti-leak property is provided. A silver oxide battery includes: a positive electrode canister (11) having a form of a cylinder with a bottom portion (11a); a negative electrode canister (12) having a form of a cylinder with a lid portion (12a) and being contained in the positive electrode canister; and an electrolytic solution contained within a space formed by the positive electrode canister and the negative electrode canister. The negative electrode canister is formed into a shape of a double-step cylinder having decreasing inner diameters toward the lid portion. The double-step cylinder has a first cylindrical portion that defines a cylindrical portion closer to the lid portion, and a second cylindrical portion that defines a cylindrical portion farther from the lid portion. The first cylindrical portion has a first inner curved surface (21is) that projects out at a first apex (P1). The second cylindrical portion has a second inner curved surface (22is) that projects out at a second apex (P2). The angle made by the bottom portion (11a) and the straight line (A) connecting the first apex and the second apex to each other ranges from 15° to 45°.
