PROBLEM TO BE SOLVED: To provide an electronic circuit in which a positional deviation of an electronic component hardly occurs in a simple constitution when the component is mounted by reflow soldering. SOLUTION: The electronic circuit 10 comprises a lead frame 20 made of a metal. The electronic component 80 is mounted on a land 21 by melting solder paste 22 printed on a surface of a land 21 of a lead frame 20 by reflow soldering in such a manner that the land 21 is recessed to a periphery of the land 21 of the frame 20.
