An electronic artificial hand comprising: a plurality of finger groups configured to perform a gripping operation through joint movement in one direction (a) or perform unfolding movement through joint movement in the other direction (b), wherein each of the finger groups includes: a body part including a power section; a plurality of knuckles: (210, 220, 230) sequentially engaged with one end of the body part; a joint part provided in the body part and between the plurality of knuckles to perform joint movement a knuckle in the one direction (a) or in the other direction (b) at a predetermined angle; a tendon path formed in each knuckle to be eccentric in the one direction (a) on the basis of the joint part; a restoring line path formed to be eccentric in the other direction (b); a tendon section having one end connected to the power section so as to be wound (a') and unwound (b') by the power section, and the other end passing through the body part and the tendon path of each knuckle to be connected to a knuckle located at the end; and a restoring line section having one end connected to the body part and the other end passing through the restoring line path of each knuckle to be connected to a knuckle located at the end, characterised in that the body part further includes at least one switch part (600, 650) configured to stop the power section by using tension of the tendon section which is variable when the power section winds (a') or unwinds (b') the tendon section. a plurality of finger groups configured to perform a gripping operation through joint movement in one direction (a) or perform unfolding movement through joint movement in the other direction (b), wherein each of the finger groups includes: a body part including a power section; a plurality of knuckles: (210, 220, 230) sequentially engaged with one end of the body part; a joint part provided in the body part and between the plurality of knuckles to perform joint movement a knuckle in the one direction (a) or in the other direction (b) at a predetermined angle; a tendon path formed in each knuckle to be eccentric in the one direction (a) on the basis of the joint part; a restoring line path formed to be eccentric in the other direction (b); a tendon section having one end connected to the power section so as to be wound (a') and unwound (b') by the power section, and the other end passing through the body part and the tendon path of each knuckle to be connected to a knuckle located at the end; and a restoring line section having one end connected to the body part and the other end passing through the restoring line path of each knuckle to be connected to a knuckle located at the end, a body part including a power section; a plurality of knuckles: (210, 220, 230) sequentially engaged with one end of the body part; a joint part provided in the body part and between the plurality of knuckles to perform joint movement a knuckle in the one direction (a) or in the other direction (b) at a predetermined angle; a tendon path formed in each knuckle to be eccentric in the one direction (a) on the basis of the joint part; a restoring line path formed to be eccentric in the other direction (b); a tendon section having one end connected to the power section so as to be wound (a') and unwound (b') by the power section, and the other end passing through the body part and the tendon path of each knuckle to be connected to a knuckle located at the end; and a restoring line section having one end connected to the body part and the other end passing through the restoring line path of each knuckle to be connected to a knuckle located at the end, characterised in that the body part further includes at least one switch part (600, 650) configured to stop the power section by using tension of the tendon section which is variable when the power section winds (a') or unwinds (b') the tendon section.
