PROBLEM TO BE SOLVED: To maintain satisfactory airtightness in a battery, without causing cracks in a solder material for bonding a terminal body to an insulating substrate, even if a compression bonded terminal is tightened with a torque such that no continuity fault with the outside occurs. SOLUTION: Relations 0.5 mm<=X<=W (1.0 mm<W) and 0.5 mm<=Y<=H (1.0 mm<H) are satisfied, where X is the protrusion width of a collar portion 2a provided at the end on the inside of a case for a terminal body 2 from the side face of the terminal body 2, Y is the thickness of the collar portion 2a, W is the thickness of the insulating substrate 1 from the inner face to the outer face of a through-hole 1a, and H is the length of the insulating substrate 1.
