A suspension board with circuit includes a metal supporting board, a conductive layer laminated on the metal supporting board, and a via layer interposed between the metal supporting board and the conductive layer. The conductive layer includes a conductive pattern, and a reference portion serving as a positioning reference for placing the suspension board with circuit on a load beam.

Suspension board and load beam combination including a positioning reference hole and a reinforcing layer

A first coil portion is formed in a first coil region of an upper surface of an insulating layer, and a second coil portion is formed on a lower surface of the insulating layer. A second terminal is formed at a position outside the first coil region. One or more intersection regions, in which a path, extending from an inner end of the first coil portion to the second terminal, intersects the first coil portion, are provided on the upper surface. The first coil portion is parted in each intersection region. A second lead portion passes between one portion and another portion of the first coil portion parted in said each intersection region and extends from the inner end of the first coil portion to the second terminal. The first coil portion and the second coil portion are connected together in parallel via through holes formed in the insulating layer.

An optical sensor module is provided in which an engagement portion of a board unit is fitted in a groove of an optical waveguide unit and, even with the single engagement portion, the board unit is stably supported. An optical sensor module includes an optical waveguide unit, and a board unit mounted with an optical element and coupled to the optical waveguide unit. The optical waveguide unit includes a single edge extension portion axially extending along one side edge of an over-cladding layer, a board unit engagement groove provided in the single edge extension portion, and a projection provided on a side wall of the vertical groove and kept in abutment against an engagement portion of the board unit. The board unit includes an engagement portion fitted in the vertical groove, which abuts against the projection within the vertical groove.

A plurality of wiring patterns are formed so as to extend in parallel with each other. A plurality of test terminals are formed in a substantially rectangular shape such that respective widths thereof increase toward respective one sides from respective ends of the plurality of wiring patterns. The plurality of test terminals in each group are arranged so as to be aligned along a length direction of the wiring patterns. The wiring patterns are formed so as to be longer in the order, and the test terminals are further away from a mounting region in the order. An interval (width of a plating resist) between the test terminals in each group and the wiring patterns in the other group adjacent thereto is set to decrease in the order.
