A valve opening and closing timing control apparatus comprising: a driving-side rotating body rotating synchronously with a crankshaft of an internal combustion engine; a driven-side rotating body arranged coaxially with an axis of the driving-side rotating body and rotating integrally with a camshaft for opening and closing valves of the internal combustion engine in a state being fixed to the camshaft by a bolt; a fluid pressure chamber defined between the driving-side rotating body and the driven-side rotating body; an intermediate lock mechanism selectively switchable between a locked state in which a relative rotational phase of the driven-side rotating body relative to the driving-side rotating body is locked at an intermediate lock phase between a most advanced angle phase and a most retarded angle phase and an unlocked state in which the locked state is released; a lock flow passage bringing a working fluid to the intermediate lock mechanism; characterized in that, the valve opening and closing timing control apparatus comprising: an electromagnetic valve including a spool which is arranged at an inner portion of the bolt and controlling supply and discharge of the working fluid relative to the fluid pressure chamber and the intermediate lock mechanism, the lock flow passage including a first flow passage which is arranged between the spool and a supply flow passage in a radial direction and which brings the working fluid to flow from the supply flow passage, towards the spool the supply flow passage bringing the working fluid supplied from a pump to flow along the axis direction at the inner portion of the bolt, the lock flow passage including a second flow passage which is provided at the inner portion of the bolt in a penetrating manner in the radial direction and which brings the working fluid to flow from the spool towards the intermediate lock mechanism, at least a portion of the first flow passage and at least a portion of the second flow passage being positioned within a same plane orthogonal to the axis. a driving-side rotating body rotating synchronously with a crankshaft of an internal combustion engine;
