PROBLEM TO BE SOLVED: To provide a printed circuit board having a connection terminal in which connection reliability can be secured and which can be made fine, a method of manufacturing the printed circuit board, and the connection terminal.SOLUTION: Read wiring patterns R1, R2 and write wiring patterns W1, W2 are formed on an insulating layer 41. Connection terminals 21-24 made of conductor are connected to the read wiring patterns R1, R2 and the write wiring patterns W1, W2, respectively. Each of the connection terminals 21-24 has at least one corner with a radius of curvature of 35 μm or less. |
