摘要: It is an object of the present invention to provide a highly reliable optical module circuit board having a sufficient mechanical strength with respect to an external stress. An optical module circuit board according to the present invention includes a flexible printed circuit having at least a multilayered structure in which a layer containing a conductive metal interconnection is sandwiched between insulating layers, wherein the flexible printed circuit includes a main body portion having the multilayered structure, a first surface mounted with an electronic component, and a second surface opposite to the first surface, a neck portion having the multilayered structure and extending from one end of the main body portion, and a head portion positioned at a distal end of the neck portion extending from the one end of the main body portion, having the multilayered structure, and mounted with an optical operation element and a bypass capacitor, Particularly, the neck portion defines the positional relationship between the main body portion and the head portion so as to give the circuit board a sufficient mechanical strength.
