A gas sensor (1) is provided with a sensor element (2), a housing (13), and an element cover (3). A tip part (201) of the sensor element (2) is provided with a gas introduction part (271). The element cover (3) has an inner cover (4) and an outer cover (5). The outer cover (5) is provided with an outer introduction-opening (52). The inner cover (4) is provided with an inner introduction-opening (42) and a louver part (44) formed so as to be bent from an axial-direction distal end-side (X1) end part (421) of the inner introduction opening (42) to the inner side of the inner cover (4), and so as to face the axial-direction proximal end-side (X2). If the louver part (44) is projected on the same surface as the inner-introduction opening (42), a pair of side end edges of the louver part (44) are formed to be substantially linear and substantially parallel with respect to a louver forming direction that goes from a blade root side to the distal end-side of the louver part (44). |
