Printed circuit board with a holder for a battery integrated into the printed circuit board, wherein the holder has a first and a second contact (21, 22), each connected to a conductor track (31, 32) of the printed circuit board, and wherein the holder is designed in such a way that a battery which can be inserted into the holder is clamped between the two contacts (21, 22) in the inserted state, - in that poles of the battery arranged on opposite end faces of the battery are each in electrically conductive connection to one of the two contacts (21, 22), and - that the battery clamped between the contacts (21, 22) is aligned in relation to the printed circuit board in such a way that an imaginary straight line connecting the poles is arranged substantially parallel to the plane of a carrier region of the printed circuit board, wherein the printed circuit board comprises a rigid first portion connected to the support region and arranged substantially perpendicular to the support region, wherein the first contact is arranged on the first portion, wherein the printed circuit board comprises a rigid second portion connected to the support region and arranged substantially perpendicular to the support region, wherein the second contact is arranged on the second portion, wherein the support region and the first section arranged perpendicularly thereto are formed by two directly adjacent rigid regions of the printed circuit board, between which a channel-shaped depression forming a bend line is provided in the printed circuit board, wherein the second section is formed by a rigid region of the printed circuit board directly adjoining the carrier region, and wherein a channel-shaped depression forming a bend line is provided in the printed circuit board between the carrier region and the second section, characterized in that that the battery clamped between the contacts (21, 22) rests on the carrier region supporting the battery and in that the carrier region has a recess, into which recess the battery can be inserted, and wherein the recess is dimensioned in particular such that a partial region of the battery inserted into the recess from a first side of the carrier region and resting on the recess projects out of the carrier region on a second side of the carrier region opposite the first side. wherein the holder has a first and a second contact (21, 22), each connected to a conductor track (31, 32) of the printed circuit board, and wherein the holder is designed in such a way that a battery which can be inserted into the holder is clamped between the two contacts (21, 22) in the inserted state, - in that poles of the battery arranged on opposite end faces of the battery are each in electrically conductive connection to one of the two contacts (21, 22), and - that the battery clamped between the contacts (21, 22) is aligned in relation to the printed circuit board in such a way that an imaginary straight line connecting the poles is arranged substantially parallel to the plane of a carrier region of the printed circuit board, - in that poles of the battery arranged on opposite end faces of the battery are each in electrically conductive connection to one of the two contacts (21, 22), and - that the battery clamped between the contacts (21, 22) is aligned in relation to the printed circuit board in such a way that an imaginary straight line connecting the poles is arranged substantially parallel to the plane of a carrier region of the printed circuit board, wherein the printed circuit board comprises a rigid first portion connected to the support region and arranged substantially perpendicular to the support region, wherein the first contact is arranged on the first portion, wherein the printed circuit board comprises a rigid second portion connected to the support region and arranged substantially perpendicular to the support region, wherein the second contact is arranged on the second portion, wherein the support region and the first section arranged perpendicularly thereto are formed by two directly adjacent rigid regions of the printed circuit board, between which a channel-shaped depression forming a bend line is provided in the printed circuit board, wherein the second section is formed by a rigid region of the printed circuit board directly adjoining the carrier region, and wherein a channel-shaped depression forming a bend line is provided in the printed circuit board between the carrier region and the second section, characterized in that that the battery clamped between the contacts (21, 22) rests on the carrier region supporting the battery and in that the carrier region has a recess, into which recess the battery can be inserted, and wherein the recess is dimensioned in particular such that a partial region of the battery inserted into the recess from a first side of the carrier region and resting on the recess projects out of the carrier region on a second side of the carrier region opposite the first side.
