PROBLEM TO BE SOLVED: To solve the problem, in the prior art of annular lands being formed around lead pass holes formed into a printed board but, if the lands are annular, opposite portions of the lands to portions at bent portions of lead terminals become wasted and bridges may be formed between the bent portions and a pattern wiring to make impossible designing, such a wiring as formed a pattern between two lands. SOLUTION: A printed board 1 comprises a board 10, a lead pass hole 3 piercing the thickness of the board 10, and a long land 11a formed around the hole 3, extending in the bending direction of a lead terminal 4 piercing the pass hole 3. A length L of the long portion of the land 11a is designed to be longer than a length d of the bent portion of the lead terminal.
