a withdrawal groove sealing portion ( 145 ) having a structure that extends from the other end of the hinge cover body portion ( 141 ) in an integral structure by a predetermined length and corresponds to a card withdrawal groove ( 126 ),

the upper body part ( 110 ) includes a hinge mounting groove ( 114 ) that is symmetrically formed on both sides of one end of the upper body part ( 110 ), has a groove structure that is recessed by a predetermined depth and extends upward by a predetermined length, and has a structure that is bound to the hinge binding portion ( 142 ) in a form that changes a vertical position of the hinge binding portion ( 142 ) of the hinge cover part ( 140 ), and

the lower body part ( 120 ) includes:

a second magnetic member ( 125 ) that is mounted on one end of the lower body part ( 120 ), is disposed at a position in contact with the first magnetic member ( 144 ), and has a polarity different from that of the first magnetic member ( 144 ); and

the card withdrawal groove ( 126 ) that is formed adjacent to the card inlet port ( 131 ) formed at one end of the lower body part ( 120 ).

2. The foldable mobile phone case of claim 1 , wherein the upper body part ( 110 ) includes:

an upper inner surface ( 111 ) having a structure that constitutes a storage space having a predetermined volume and is mounted to surround an upper portion of the to-be-mounted mobile phone;

a lens exposure portion ( 112 ) having a structure in which a hole is formed to pass through one surface so that the camera lens of the to-be-mounted mobile phone is exposed to the outside; and

a button exposure portion ( 113 ) having a structure in which a portion is formed to be recessed in one surface so that a button formed on a lateral side of the to-be-mounted mobile phone is exposed to the outside.

3. The foldable mobile phone case of claim 1 , wherein the lower body part ( 110 ) includes:

a lower inner surface ( 121 ) that constitutes a storage space having a predetermined volume and is mounted to surround a lower portion of the to-be-mounted mobile phone;

a terminal exposure portion ( 122 ) having a structure in which a hole is formed to pass through one surface so that a charging terminal of the to-be-mounted mobile phone is exposed to the outside;

a recessed groove ( 123 ) having a structure that extends in an extension lengthwise direction of the lower body part ( 120 ) along both sides of the card storage part ( 130 ) formed on the lower inner surface ( 121 ) and is recessed by a predetermined depth; and

a reinforcement portion ( 124 ) having a structure that is fixedly seated on the recessed groove ( 123 ), extends to an edge of the lower inner surface ( 121 ), and surrounds a lower edge portion of the to-be-mounted mobile phone.
