Printed wiring board connecting structure

摘要

[Object] To provide a printed wiring board connecting structure that enables a board to be easily manufactured, and good and reliable electrical connections to be achieved. [Means for Settlement] The printed wiring board connecting structure includes: a child board 1 having a plurality of connecting pieces 11 each formed with a first connecting pattern 100; and a mother board 2 having a plurality of connecting holes 21 that are to be inserted with the respective connecting pieces 11, and is configured such that a circumferential part and an inner circumferential surface of each of the connecting holes 21 is formed with a second connecting pattern 20 that is to be electrically connected to the first connecting pattern 10, and by inserting each of the connecting pieces 11 1 into each of the connecting holes 21, and soldering the respective connecting patterns 10 and 20 to each other, the respective boards 1 and 2 are electrically and mechanically connected to each other, wherein each of the connecting pieces 11 has a through-hole 12 that penetrates in a thickness direction and has an inner circumferential surface covered with an electrically conductive material, and a part of the through-hole 12 is, upon the soldering, exposed outside of the connecting hole 21.
