[Means for Solution] In an internal combustion engine 1 which includes a combustion pressure sensor incorporated glow plug 20A and sensor nonincorporated glow plugs 20B, a first plug regression line Lp1 and the second plug regression line Lp2 are in such a relation that, at any temperature Tx within the temperature range Tr, a second voltage Vp2x is lower than a first voltage Vp1x; the resistance RB2a of a second electricity supply line 310B is greater than the resistance RB1a of a first electricity supply line 310A; and a first section regression line Lc1 and a second section regression line Lc2 are in such a relation that, at any temperature Tx within the temperature range Tr, an overall voltage deviation |vc1x - Vc2x|, which is the absolute value of the difference between a third voltage Vc1x and a fourth voltage Vc2x, is smaller than a first-second plug voltage difference (Vp1x - Vp2x).",
