A silicone hydrogel comprising a repeating unit derived from a monofunctional linear silicone (meth)acrylate and a repeating unit derived from a hydrophilic (meth)acrylate, further comprising a repeating unit derived from a monofunctional silicone (meth)acrylate different from the monofunctional linear silicone (meth)acrylate, wherein the content of the repeating units derived from the (meth)acrylates is more than 80% by mass based on the amount of the silicone hydrogel, wherein the hydrophilic (meth)acrylate is a hydrophilic monomer, and the hydrophilic monomer is a monomer that is uniformly dissolved when mixed with water at a monomer/water ratio of 10/90 (mass ratio) at 25°C, wherein the linear silicone in the monofunctional linear silicone (meth)acrylate refers to a structure in which when a line is drawn along a siloxanyl bond (bond formed by repetition of -Si-O-) in silicone with a silicon atom as a starting point, the silicon atom being bonded to an organic group having a (meth)acryloyloxy group, the line is formed as a single line having no branch, wherein the monofunctional linear silicone (meth)acrylate is represented by the following general formula (a): wherein R 1 represents hydrogen or a methyl group; R 2 represents an optionally substituted divalent organic group having 1 to 20 carbon atoms; R 3 to R 6 each independently represent an optionally substituted alkyl group having 1 to 20 carbon atoms or an optionally substituted aryl group having 6 to 20 carbon atoms; R 7 represents an optionally substituted alkyl group having 1 to 20 carbon atoms or an optionally substituted aryl group having 6 to 20 carbon atoms; and n represents an integer of 1 to 200 which optionally has distribution, wherein the monofunctional silicone (meth)acrylate different from the monofunctional linear silicone (meth)acrylate is represented by the following general formula (b): wherein R 14 represents hydrogen or a methyl group; R 15 represents an optionally substituted divalent organic group having 1 to 20 carbon atoms; R 16 to R 19 each independently represent an alkyl group having 1 to 20 carbon atoms, or an aryl group having 6 to 20 carbon atoms; and k represents an integer of 0 or 1. wherein the linear silicone in the monofunctional linear silicone (meth)acrylate refers to a structure in which when a line is drawn along a siloxanyl bond (bond formed by repetition of -Si-O-) in silicone with a silicon atom as a starting point, the silicon atom being bonded to an organic group having a (meth)acryloyloxy group, the line is formed as a single line having no branch, wherein the monofunctional linear silicone (meth)acrylate is represented by the following general formula (a): wherein R 1 represents hydrogen or a methyl group; R 2 represents an optionally substituted divalent organic group having 1 to 20 carbon atoms; R 3 to R 6 each independently represent an optionally substituted alkyl group having 1 to 20 carbon atoms or an optionally substituted aryl group having 6 to 20 carbon atoms; R 7 represents an optionally substituted alkyl group having 1 to 20 carbon atoms or an optionally substituted aryl group having 6 to 20 carbon atoms; and n represents an integer of 1 to 200 which optionally has distribution, wherein the monofunctional silicone (meth)acrylate different from the monofunctional linear silicone (meth)acrylate is represented by the following general formula (b): wherein R 14 represents hydrogen or a methyl group; R 15 represents an optionally substituted divalent organic group having 1 to 20 carbon atoms; R 16 to R 19 each independently represent an alkyl group having 1 to 20 carbon atoms, or an aryl group having 6 to 20 carbon atoms; and k represents an integer of 0 or 1. wherein R 1 represents hydrogen or a methyl group; R 2 represents an optionally substituted divalent organic group having 1 to 20 carbon atoms; R 3 to R 6 each independently represent an optionally substituted alkyl group having 1 to 20 carbon atoms or an optionally substituted aryl group having 6 to 20 carbon atoms; R 7 represents an optionally substituted alkyl group having 1 to 20 carbon atoms or an optionally substituted aryl group having 6 to 20 carbon atoms; and n represents an integer of 1 to 200 which optionally has distribution, wherein the monofunctional silicone (meth)acrylate different from the monofunctional linear silicone (meth)acrylate is represented by the following general formula (b): wherein R 14 represents hydrogen or a methyl group; R 15 represents an optionally substituted divalent organic group having 1 to 20 carbon atoms; R 16 to R 19 each independently represent an alkyl group having 1 to 20 carbon atoms, or an aryl group having 6 to 20 carbon atoms; and k represents an integer of 0 or 1.
