Claim:
A refrigerator comprising: a case forming an inner space of the refrigerator; and a door configured to open or close the inner space, wherein the case comprises: an outer plate; an inner plate disposed at an inner side of the outer plate and forming the inner space; foam located between the outer plate and the inner plate; and a reinforcing component disposed at an inner side of the outer plate and contacting the foam, wherein the reinforcing component is formed by a pultrusion method by mixing a base component made of synthetic resin and a supplement component formed by arranging reinforcing fibers, wherein the reinforcing component comprises: a first reinforcing component disposed at a front surface of the outer plate; and a second reinforcing component installed at a corner of a bottom of the case or at a mechanic chamber, wherein the reinforcing component is superior to iron in a specific strength, wherein the first reinforcing component has a length corresponding to 60% to 95% of an overall height of the refrigerator, wherein the second reinforcing component simultaneously supports the bottom of the refrigerator and a rear surface of a lower portion of the refrigerator, wherein the second reinforcing component has a first member supporting the bottom of the refrigerator, a second member supporting the rear surface of the lower portion of the refrigerator, and connection members attached on the surfaces of the first member and second member, wherein the second reinforcing component has an arrangement direction of reinforcing fibers forming the supplement component, the arrangement direction being different from that of the first reinforcing component, wherein the supplement component of the second reinforcing component is formed by staking at least two or more fibrous layers with fibers arranged in two directions to cross each other to tolerate the higher strength, wherein the first member comprises two contact surfaces perpendicular to each other and a bending portion bent respectively from the two contact surfaces, a first contact surface of the two contact surfaces of the first member being disposed at the bottom of the refrigerator, and a second contact surface of the two contact surfaces of the first member being horizontally disposed at the side wall of the refrigerator, wherein the second member comprises two contact surfaces perpendicular to each other and a bending portion bent respectively from the two contact surfaces, a first contact surface of the two contact surfaces of the second member being disposed at the rear wall of the refrigerator, and a second contact surface of the two contact surfaces of the second member being vertically disposed at the side wall of the refrigerator, and wherein one of the connection members connects the first contact surface of the first member with the first contact surface of the second member, and an other of the connection members connects the second contact surface of the first member with the second contact surface of the second member.
