1. An imaging lens assembly module, comprising:
an imaging lens assembly comprising a plurality of plastic lens elements, and defining a first optical axis passing through the plastic lens elements;
a light path folding element for a light entering thereinto along a second optical axis and folding the light along the first optical axis entering into the imaging lens assembly;
a first lens barrel containing one or more of the plastic lens elements;
a second lens barrel containing another one or more of the plastic lens elements;
a base, the first lens barrel and the second lens barrel mounted thereon;
a plurality of rolling bearings interposed between the first lens barrel and the base and the second lens barrel and the base, respectively, which is for allowing the first lens barrel and the second lens barrel being relative to the base and displaceable along the first optical axis;
a first magnet pair fixed on the first lens barrel and comprising two magnets which are circumferentially disposed about the first optical axis, wherein one of the two magnets of the first magnet pair is a first sensing magnet and is disposed correspondingly to a first Hall sensing element, and the first Hall sensing element is for detecting a displacement of the first lens barrel along the first optical axis; and
a coil member, wherein the first sensing magnet does not face the coil member;
wherein the base comprises a guiding groove structure facing towards the first lens barrel and the second lens barrel, and the guiding groove structure extends along a direction parallel to the first optical axis;
wherein the rolling bearings interposed between the first lens barrel and the base and the rolling bearings interposed between the second lens barrel and the base are interposed in the guiding groove structure.
