Fiber, fiber aggregate and adhesive having the same

A fiber aggregate, comprising:

• a plurality of fibers each comprising a carrier polymer and a plurality of functional particles, wherein the functional particles are embedded in the carrier polymer to be physically fixed to the carrier polymer,
• wherein the plurality of fibers are tangled to form the fiber aggregate,
• wherein the carrier polymer comprises coating parts each configured to coat a respective one of the functional particles and extension parts extended in a length direction and configured to connect the functional particles,
• wherein a thickness of the coating part is approximately 0.1% to approximately 50% of a radius of the respective one of the functional particles, wherein the extension parts are configured to fix distances between the coating parts embedding the functional particles to maintain a dispersed state between the functional particles.
