Claims (1)

[Claims for Utility Model Registration] (1) A plurality of desired electronic circuits are formed, and a series of through-holes and break grooves are provided between the through-holes along the boundaries of the electronic circuits, When forming the electronic circuit by printing, a conductive paste is also printed on the inner wall surface of the through hole, and by cutting along the boundary line, the electronic circuit can be divided into individual circuits, and the conductive paste after the division is In a circuit board in which the inner wall surface of the through-hole printed with paste serves as a terminal for connecting a lead wire, the break groove is made shorter than the interval between the through-holes, and the break groove is interrupted between the through-holes. A circuit board characterized by comprising: (2) In paragraph (1) of claims for utility model registration,
A circuit board characterized in that the break groove is composed of a plurality of discontinuous grooves.
