PROBLEM TO BE SOLVED: To provide a printed board capable of surely generating a groove for locking a tip of a probe pin, and responding even to component mounting dispersion.SOLUTION: This printed board 1 includes a pair of lands 2, 2 having the same shape for surface-mounting a chip type electronic component 10. Wire patterns 3, 3 of the lands 2, 2 are covered with solder resist 4, and solder resist 5 is arranged on each land 2. The solder resist 5 is linear resist of a length from the front end 21 of the land 2 to the rear end 22 thereof. The solder resist 5 is formed nearly at the center part of the upper surface of the land 2 to be directed in the arrangement direction of the pair of lands 2, 2. Preferably, the line width d of the land 2 is set ≤1/3 of the width w of an external electrode 12 and not smaller than the diameter of the tip 201 of a probe pin 200. |
