PURPOSE: Laser processing apparatus and method using the electric field are provided to enable users to process an object using the low laser output by reducing the value of a critical point of light quantity. CONSTITUTION: A laser processing apparatus(1) using the electric field includes an electric field generator(104) and a laser generation unit(100). The electric field generator generates the electric field on a product for increasing the energy state of the processed product(102). The laser generation unit radiates laser to the product with the increased energy by the electric field for processing.
