The optical waveguide is slack in the opening.
Claims3
A suspension board with circuit comprising:
- a circuit board formed with an opening, and having a mounting portion defined by the opening for mounting thereon a slider on which a magnetic head is mounted;
- and
- an optical waveguide disposed on the circuit board so as to traverse the opening, wherein
- the optical waveguide is slack in the opening.

A producing method of a suspension board with circuit, the producing method comprising:
- preparing a circuit board formed with an opening, and having a mounting portion defined by the opening for mounting thereon a slider on which a magnetic head is mounted;
- preparing an optical waveguide;
- and
- disposing the optical waveguide on the circuit board such that the optical waveguide traverses the opening, wherein,
- in the step of preparing the circuit board, locking portions for locking the optical waveguide are formed on both sides of the opening interposed therebetween,
- in the step of preparing the optical waveguide, respective locked portions to be locked by the respective locking portions are provided such that a distance between the two locking portions formed on both sides of the opening is shorter than a distance between the two locked portions corresponding to the two locking portions, and,
- in the step of disposing the optical waveguide, the respective locked portions are locked by the respective locking portions, while the optical waveguide between the two locked portions corresponding to the two locking portions formed on both sides of the opening is slackened.
