Provided are an igniter and a gas generator that suppress inhibition of fire transfer to an enhance agent by adjusting elongation of a cup-shaped member at the time of activation while maintaining sealability and insulation. A disk-type gas generator 100 has a short substantially cylindrical housing in which one end and the other end in an axial direction are closed, and a holder 30, an igniter 40 including a squib cover 43, a cup-shaped member 50, an enhance agent 59, a gas generating agent 61, a lower support member 70, an upper support member 80, a cushion material 85, a filter 90, and the like as internal components are accommodated in an accommodation space provided inside the housing. The squib cover 43 is formed by molding a thermosetting resin or a thermoplastic resin containing an elongation percentage adjusting material into a cup shape in order to set an elongation percentage at the time of activation of the igniter 40 to be greater than 0% and less than 10%.
