Provided are: a circuit device which has improved connection reliability in a solder joint portion by suppressing the occurrence of sink of solder; and a method for manufacturing the circuit device. In a method for manufacturing a circuit device of the present invention, a plurality of solders (19), which are apart from each other, are firstly formed on the upper surface of a pad (18A), and a chip component (14B) and a transistor (14C) are affixed at the same time. After that, a solder paste (31) is supplied to the upper surface of the pad (18A) using a syringe (30), a heatsink (14D) is mounted on top of the solder paste (31), and melting is caused by a reflow process. There is little risk of sinking of the solders (19) in the present invention since the solders (19) are discretely arranged on the upper surface of the pad (18A). |
